AWS A5.18 - это спецификация электродов и стержней из углеродистой стали для дуговой сварки в защитной среде, такой как газовая дуга (GMAW), газовая вольфрамовая дуга (GTAW) и плазменная дуга (PAW). Все мы знаем, что электроды класса ER70S-2、ER70S-3、ER70S-4、ER70S-6、ER70S-7 могут использоваться для сварки углеродистой и низколегированной углеродистой стали с прочностью менее 500 МПа, [...].
MAG welding is also known as “metal active gas welding”, is a gas shielded arc welding method by adding a certain amount of active gas such as O2 , CO₂, etc., in the inert gas argon. MAG is characterized by its good welding quality, high efficiency, easy automation and other advantages that can be used for welding in […]
Due to the small thermal conductivity and large linear expansion coefficient, the welding of Austenitic stainless steel is easy to produce deformation, so the welding method with linear energy concentration should be selected as far as possible. MIG welding (Molten inert gas shielded welding) using a molten electrode, with external gas as arc medium, and protect […]
