How to choose welding machine
Gas Welding Exhaust Pipeline with appropriate rated current shall be selected according to the required welding current and the actual load duration.3.4 the welder shall be maintained by special personnel and maintained regularly;In case of failure, stop the machine immediately for maintenance.4 weldersWelders must go through theoretical study and practical training of carbon dioxide gas shielded welding, and pass the examination and obtain the corresponding qualification certificate before engaging in relevant welding work.5 welding5.1 welding preparation5.1.1 appropriate welding auxiliary devices must be selected according to welding position, joint form and operating efficiency;5.1.2 check the welding machine and auxiliary equipment strictly, and ensure the normal operation of circuit, waterway, air route and mechanical device;5.1.3 groove form and size of automatic and semi-automatic welding are related to joint form, plate thickness, welding position, construction conditions and other factors.If the welding nozzle does not need to extend into the groove, the groove Angle should choose the lower limit;5.1.4 the penetration depth of non-full penetration welding S≥ 0.7delta, otherwise the specific data of penetration depth should be noted;5.1.5 the welding wire, groove and its surrounding area within 10-20mm must be kept clean and free of rust, grease, water, paint and other foreign matters affecting the welding quality;
