Inclusions should be prevented by taking care to avoid touching the surface with the pure tungsten electrode. Argon with or without helium can be used as a shield. Helium helps generating a hotter arc if necessary.See all results for this question
What causes sugaring on the backside of a stainless steel weld?
Figure 8 shows sugaring on the backside of a stainless steel weld. Sugaring (oxidation) occurs around the weld when it is exposed to oxygen in the air. The best way to prevent sugaring is to back purge the weld with argon shielding gas or reduce welding amperage.See all results for this questionWelding processes for wear resistant overlays - ScienceDirectJan 01, 2014 · The following sections present a brief overview of materials systems typically used for wear resistant overlays and a detailed description of the key processes used to deposit these materials systems: plasma transfer arc welding, submerged arc welding, laser beam welding, gas metal arc welding-related processes using tubular wires, brazing, and s316 photo etching plates Submerged arc weldingWelding of P-91 Plates - Home - SpringerJun 27, 2016 · P-91 is modified 9Cr1Mo steel.
