Which is better hydrogen welding or argon arc welding?
And there has a tendency to crack when water quenching. The hydrogen welding and argon arc welding is good for it, but the gas welding is not. It is required to preheat before the welding, and stress relief annealing should be performed after welding.See all results for this questionWhich is better AISI 1045 or JIS s45c?AISI 1045 steel is high-quality medium-carbon steel with high strength. It also can be called JIS S45C and DIN C45 steel. It is usually used in normalized condition because of its bad hardenability.See all results for this questionWhat kind of tungsten is used in arc welding?Gas Tungsten Arc Welding (GTAW) also referred to as Tungsten Inert Gas (TIG) uses a non-consumable tungsten electrode to produce the weld. Under the correct welding conditions, the tungsten electrode does not melt.See all results for this question
What kind of gas is used in arc welding?
Most metals oxidize rapidly in their molten state, and therefore, the weld area needs to be protected from atmospheric contamination; this is achieved in gas tungsten arc welding GTAW by a shielding gas (argon, helium, nitrogen).See all results for this questionWelding process of ASTM A335 P91 Pipe-Boiler Tubes,Heat jis sma400cp properties Argon arc weldingShielding gas: argon, purity 99.99%, argon flow: 8-12l / min for welding gun, 10-25l / min for the first pass on the back, 3-8l / min for the second pass. Interlayer temperature: 250 (temperature controlled by far infrared detector). Post heat treatment: temperature rise to 300-350 after welding, and heat preservation for 2h.Welding of low temperature steel pipeMar 30, 2020 · For low temperature steel pipe (ASTM A333), the commonly used welding methods are electrode arc welding, submerged arc automatic welding, argon tungsten arc welding and gas fusion arc welding. The welding current should not be too large. At the same time, the temperature between the welding channels should be controlled.
