The cracking susceptibility of SPV50Q steel weldment by manual electric arc welding has been investigated in various solutions with different concentrations of H_ 2 S. The results of slow strain rate testing, performed at a strain rate of 1×10~ -6 s~ -1 , reveal the presence of SSCC and HIC in the zone of HAZ adjacent to weldment.
The article compares several scheme of movement system scheme of non-standard state pipe cross through line automatic electric arc welding and give out best movement control design scheme of cross through line automatic electric arc welding of exhaust pipe manifold of SATANA car.
Abstract Aluminizing can significantly raise resistance of steel tubes to high-temperature oxidation and corrosion Aluminized tubes are connected to tube sheet by manul electric arc welding The check results show that welding quality is satisfactory whether with T427 welding rod or E1-23-12Mo2-16
After measuring calculates, the welding speed of vertical position gas-electric welding is 1.5 times of core welding wire protective automatic vertical position welding & 15 times of handwork electric arc welding. It has raised welding efficiency.
Lincoln weld is used in heat-resistant steel welding instead of manual electric arc weld. Sintered flux SJ101 and soldering wire H13CrMoA are used together to evaluate the welding process. Through examination,it meets the requirements specified in JB4708-2000.This sintered flux is very good with excellent ductibility.
The paper emphatically analyzes the influence on the welding quality of the welding technology, the testing and research of the welding technology for E70-1 drug welding wire with CO2 electrical arc welding used the high strength steel with the grade of strength over 500Mpa is carried out , and the reasonable welding technology is established.
Fifty-four healthy men using two electric arc welding processes (manual metal arc on stainless steel and mild steel, and metal inert gas on mild steel) were studied.
Effect of electron transfer on the cold resistance of the near-seam zone in electric arc welding
Al2O3-Si3N4 electrode holders for the electric arc welding of metals were subjected to tests under industrial conditions, in which their useful life was found to be 25 times longer than that of similar electrode holders made of porcelain.
Fatigue resistance of manual electric arc welding joints in high-strength 14Kh2GMR steel
A description of each major type of electric arc welding process is provided below.
