Welder (special equipment welding operator) examination items
Thread Content
Dear friends, if you hold the welder project (pipe butt jointing) GTAW-FeⅣ-6G-5/57-FefS-02/11/12, is it necessary to take the GTAW-FeⅣ-1G-5-FefS-02/11/12 project again?
There is no problem with the coverage. There is no need to take the test again. However, you should pay attention to the 11 process for this project because it does not have a back protective gas. Single-sided welding, double-sided molding and back protection cannot be used.
Please take a look at Article A.4.3.9 in TSG Z6002
Doesn’t it say here that 11 cannot be substituted for 10?
11 items can be welded to 10 items.
Are you remembering it wrong? If you think about it logically, it is definitely possible to solder those without back protection to those with back protection.
Is it okay to weld FeⅣ materials without back protection?
The stainless steel test argon arc welding test back guarantee can cover those without back guarantee.
Thanks for the reminder, it was indeed written backwards :lol, but stainless steel argon arc welding projects rarely see projects that do not require back protection, and carbon steel is more common without back protection.
