5 things welders need to know about weld positioners

Gravity helps the welder in a downhill weld,resulting in equal legs on fillet welds,smoother bead surface,and reduced cleanup and rework times.By combining a positioner with a welding power source and a torch stand,a welder can perform semiautomatic welding12345NextThe Importance of Correct Post Weld Heat Treatment (PWHT Post Weld Heat Treatment is a mandatory requirement for the fabrication and construction of pressure vessels.The residual stresses formed during welding can cause metal failures.The macro structure also changes during the welding process and makes the steel weak.PWHT removes these stresses and restores the macro structure of the steel.(PDF) Stress analysis and strength assessment of ammonia the inner side of the shell-to-bottom fillet weld which is the connecting position between weld and base zone.In order to improve the accuracy of stress calculation of large non -anchored crude oil
