Brief introduction what are the main industrial standards for welding in the US and EU?
What are the main standards of the American Welding Association (AWS)?
The American Welding Association or AWS Welding standards are shared with ANSI International.
The AWS D1 standard provides an overview of the standards for welding steel and steel alloys.
ANSI/AWS 9, for example.
1 is the standard of sheet metal welding. ANSI/AWS D10.
Recommended Procedures for welding low carbon steel are outlined in 12, while ANSI/AWS d11.
2 is the standard for welding cast iron.
The AWS C5 Standard series gives recommended practices for welding.
The AWS C3 standard series provides specifications for different types of brazing.
AWS D8 provides standards for welding automotive components.
The AWS D14 standard gives specifications for welding equipment and machinery such as welding construction equipment.
The AWS A5 series provides an overview of the specifications for filling materials used in welding.
Welding temperature the temperature of the metal passed by the standard welding will affect the welding quality. AWS D1.
1 welding is prohibited if the metal is below freezing point, set to 32 ° f or 0 ° c.
For tempered or tempered steel, the intermediate temperature is not allowed to exceed 38mm °c if the temperature is less than 205.
For objects exceeding 38mm, the temperature between channels cannot exceed 30 °c. AWS D1.
1 No need to warm up if you do electronic operationgas welding.
ISO 13916 outlines the pre-determination
Heating Temperature and intermediate temperature.
Welding test standards standard welding test methods ensure that the same quality standards are used in both construction and metal assembly wherever work is performed.
ASTM E317 outlines the process of testing welds using ultrasonic pulses.
ISO 10160 is suitable for ultrasonic testing of flat steel with a thickness of at least 6mm.
ISO 12094 is the standard for ultrasonic inspection of welded pipe.
ASTM A578 is another standard for ultrasonic examination.
Asme sa 275 describes the test procedure for checking steel forgings through magnetic particle testing. AWS C3.
8 the recommended method for checking the brazing joint is given. AWS B4.
0 The standard mechanical test methods for welds are outlined. AWS B4.
0M is the same standard, but in units of measure.
ISO 10564 outlines ISO-approved sampling methods for soft welding materials for further testing.
ISO 17635 gives a non-
Destructive Test of weld of metal material.
ISO 1106 is the original standard for X-ray inspection of welding pieces.
The standard issued in 1969 has been revoked.
Although most Welding standards involve non-
Destructive testing, there are also criteria for destructive testing to determine the quality of the weld.
ISO 4136 describes destructive welding test procedures using lateral tensile tests.
ISO 5173 outlines bending tests that can be performed on welds.
The criteria for welding acceptance used to determine whether welding is acceptable depends on the object welded.
For example, ASME b31.
3 the acceptance criteria for welds on pressure pipes are defined, while API standard 1104 determines the acceptance criteria for pipe welding. AWS D1.
1 suitable for structural welding such as welding of steel structure.
ISO 13920 provides ISO tolerances for welding structures.
AWS statement, non
Destructive testers or non-destructive testers shall meet at least AWSQCI Level II. A non-
If under the supervision of the AWSQCI Level II manager, the destructive tester at AWSQCI level can also work.
Welding equipment standard ISO 669 is the standard for resistance welding equipment.
ISO 5821 is the standard for the resistance welding electrode cap, while ISO 5182 gives the specification of the material used in the resistance welding electrode.
ISO 8206 describes the process of acceptance testing of oxygen cutting equipment.
In the European welding standard in the UK, the welding procedure must meet the BS 5135 standard.
ISO 5184 is the standard for resistance welding electrodes.
This standard is part of the UK standard BS 25184.
BS 5400 gives the standard for welding steel bridges in the UK.
EU standard EN 440 puts forward requirements for wire electrodes for gas protection metal arc welding for steel.
Welding safety standard welding circuit is not grounded.
This means that the welding power supply must be well insulated so that the main voltage does not affect the secondary circuit.
IEC 60974-
1 when using DC, the maximum peak voltage required is 113 v.
The ISO 7286 standard welding symbol gives the ISO approved symbol for resistance welding equipment.
ISO 7287 lists the graphical symbols used on hot cutting equipment.
ISO 2553 is the ISO standard used to represent symbols for welding and brazing joints. AWS A2.
4 Standard symbols for welding and non-welding
Destructive welding test.
