Which code covers structural welding of steel?
ASME Section I
AWS D1.1
ISO 9001
API 1104
AWS D1.1 is the American Welding Society standard specifically covering structural steel welding requirements. Other codes like ASME Section I address boilers, while ISO 9001 is a quality management standard. API 1104 applies to pipeline welding rather than structural steel.
What does WPS stand for in welding codes?
Weld Procedure Standard
Welding Process Specification
Welding Procedure Specification
Weld Performance Statement
WPS stands for Welding Procedure Specification, which is a document that details the welding parameters and variables. It guides welders to ensure consistent and code-compliant welds. Other terms listed are not correct code terminology.
Which nondestructive testing method uses high-frequency sound waves to detect subsurface defects?
Radiographic Testing
Magnetic Particle Testing
Ultrasonic Testing
Liquid Penetrant Testing
Ultrasonic Testing uses high-frequency sound waves to detect subsurface and internal discontinuities. Radiographic testing uses X-rays or gamma rays, while magnetic particle and liquid penetrant are surface methods. Ultrasonic is specifically for subsurface defect detection.
Why is preheat applied before welding carbon steel components?
To increase cooling rate
To remove surface oxides
To reduce hydrogen-induced cracking
To eliminate slag inclusions
Preheat reduces the cooling rate and lowers the risk of hydrogen-induced cracking by allowing hydrogen to diffuse. It also helps prevent cold cracking in the heat-affected zone. It is not applied to remove oxides or slag.
In a WPS, which of the following is considered an essential variable?
Shielding gas flow rate within tolerance
Base metal thickness outside qualified range
Ambient temperature
Welding operator's name
Essential variables are conditions that, if changed beyond specified ranges, require requalification of the WPS. Base metal thickness outside the qualified range is an essential variable. Non-essential items like operator name do not affect code compliance.
Which section of the ASME Boiler and Pressure Vessel Code covers welding procedure and welder qualifications?
Section I
Section VIII
Section IX
Section XI
ASME Section IX specifically addresses welding procedure and welder performance qualifications. Section I covers power boilers, VIII covers pressure vessels, and XI deals with in-service inspection. Qualification rules are contained in Section IX.
According to AWS D1.1, what is the maximum interpass temperature typically allowed for carbon steel structural welding?
100°F (38°C)
250°F (121°C)
350°F (177°C)
500°F (260°C)
AWS D1.1 often specifies a maximum interpass temperature of 350°F (177°C) for carbon steel to prevent overheating and maintain proper microstructure. Lower temperatures risk lack of fusion, while higher temperatures can degrade the steel. This value is common in structural welding guidelines.
Which test is commonly required for qualifying a welding procedure on a PQR in ASME Section IX?
Radiographic Test
Tensile Test
Bend Test
Macro Etch Test
ASME Section IX requires bend tests to demonstrate ductility and absence of significant defects in welded specimens. Tensile tests measure strength but are not the primary required test, and radiographic or etch tests may be used for examination but are not the core qualification test.
Under OSHA regulations, which standard addresses ventilation requirements during welding operations?
29 CFR 1910.1000
29 CFR 1910.252
29 CFR 1926.353
29 CFR 1926.501
OSHA 29 CFR 1910.252 covers welding, cutting, and brazing, including required ventilation to control fumes, gases, and particulates. Other standards relate to noise, fall protection, or general air contaminants but not specifically welding ventilation.
Which welding defect is characterized by incomplete penetration at the root of a butt joint?
Incomplete penetration
Incomplete fusion
Undercut
Porosity
Incomplete penetration occurs when the weld metal fails to extend through the joint thickness, leaving an unfilled root. Incomplete fusion is lack of bonding within the weld, while undercut and porosity are different defect types. Penetration refers specifically to root fill.
In the AWS electrode classification E7018, what does the 'S' signify?
Self-shielded
Spray transfer
Solid wire electrode
Special application
In AWS classifications, 'S' denotes a solid wire electrode covered with shielding flux. E7018 is a solid electrode with a basic flux coating. Self-shielded or spray transfer do not apply to the 'S' in this context.
What does PWHT stand for in welding codes?
Partial Weld Heat Treatment
Pre Weld Heat Treatment
Post Weld Heat Treatment
Pressure Weld Heat Treatment
PWHT stands for Post Weld Heat Treatment, a process applied after welding to relieve residual stresses and improve metallurgical properties. Pre-weld or partial treatments are different processes with other abbreviations.
Which nondestructive inspection method uses magnetic fields to detect surface and near-surface discontinuities?
Radiographic Testing
Liquid Penetrant Testing
Magnetic Particle Testing
Ultrasonic Testing
Magnetic Particle Testing uses magnetic fields and ferrous particles to reveal surface and near-surface defects in ferromagnetic materials. Radiography uses radiation, penetrant testing uses dyes, and ultrasonic testing uses sound waves.
Which code is primarily used for the welding of pressure vessels and boilers?
ISO 9001
API 650
ASME Section VIII
AWS D1.1
ASME Section VIII of the Boiler and Pressure Vessel Code governs design, fabrication, and inspection of pressure vessels, including welding requirements. AWS D1.1 covers structural steel, API 650 covers storage tanks, and ISO 9001 is a quality management standard.
What is the purpose of a Procedure Qualification Record (PQR)?
Verifying a welding procedure produces acceptable welds
Listing material suppliers
Documenting welder certification
Recording equipment settings only
A PQR documents the actual welding parameters and the successful testing of welds to ensure a WPS will produce acceptable results. It is not a record of welder certification, supplier lists, or equipment settings alone.
Which change to a welding procedure specification is considered an essential variable requiring procedure requalification under AWS D1.1?
Changing welding current within approved range
Changing the welding process from SMAW to GMAW
Varying the interpass cleaning method
Adjusting torch angle within approved range
Changing the welding process (for example from SMAW to GMAW) is an essential variable in AWS D1.1 and requires requalification. Minor adjustments within approved ranges, like torch angle or current, are non-essential if they stay within specified limits.
According to ASME Section IX, what is the qualified range of base metal thickness for a groove weld when the test coupon thickness is T?
0.25T to 1.5T
0.75T to 1.25T
0.5T to 2T
1T to 3T
ASME Section IX permits qualification of a groove-welded WPS for thicknesses from 0.5 times to 2 times the thickness of the test coupon. Other ranges listed do not reflect the code allowance for base metal thickness range.
In AWS D1.1, at what maximum Vickers hardness (HV) level in the heat-affected zone does carbon steel require post-weld heat treatment?
150 HV
200 HV
350 HV
300 HV
AWS D1.1 typically requires PWHT for carbon steels when HAZ hardness exceeds 200 HV to avoid brittle fracture. Hardness values above this threshold indicate risk of cracking and necessitate heat treatment.
What is a primary difference between AWS D1.1 and ISO 5817 regarding acceptance criteria for welding discontinuities?
Both use identical acceptance criteria but different terminology
AWS D1.1 uses quality levels B, C, and D while ISO 5817 uses pass/fail limits
ISO 5817 defines quality levels B, C, and D while AWS D1.1 uses acceptance criteria tables
ISO 5817 applies only to aluminum
ISO 5817 specifies three quality levels (B, C, D) for discontinuity acceptance, while AWS D1.1 provides tables of accept/reject limits without tiered quality levels. The two standards use different frameworks for acceptance.
Under ASME Section IX, when is Charpy V-notch impact testing required in a procedure qualification?
When the keel thickness exceeds 2 inches
For all carbon steel welds regardless of service
Only for stainless steel procedures
When the intended service temperature is below 0°C (32°F)
ASME Section IX mandates Charpy V-notch impact testing for procedure qualifications when the intended service temperature is below 0°C (32°F) to ensure toughness at low temperatures. It is not universally required for all materials or thicknesses.
