Measures to ensure welding quality include:
1. Human factors are the focus of welding control of gas -galvanized pipes. Due to the lack of necessary post -welding control methods, it is easy to cut corners and affect the quality. At the same time, the welding special characteristics of galvanized pipes make it difficult to guarantee the welding quality. Therefore, before the project starts, a welder that is skilled and holds the corresponding boiler pressure container or the same welding certificate should be selected to conduct necessary technical training and explanations, and on -site welders assessment and recognition based on the boiler conditions. Rules of pressure vessel welders. Allowing the welding site. Do not change at will to ensure that the welders of the welding pipe are relatively stable.
2. Welding material control: Ensure that the purchased welding material comes from regular channels, with a quality assurance document and a qualified certificate, which meets the process requirements. Flowing, dosage: Welded materials must be baked strictly according to the process, and the welding material must not exceed half a day.
3. Welding machine: Welding machine is a tool for welding, which must ensure reliable performance and meet process requirements; welding machines must have a qualified current and voltage table to ensure the correct implementation of the welding process. Welding cables should not be too long, and welding parameters should be adjusted when long.
4. Welding process method: Make sure the special operation method of galvanized galvanized pipes is strictly implemented, conduct pre -welding slopes inspections according to the welding process, control the welding process parameters and operation methods, check the appearance quality after welding, and add non -destructive test after welding is added after welding Essence Control the welding level and the number of welded consumables.
5. Welding environment control: Ensure that the temperature, humidity, and wind speed during welding meet the process requirements. Welding is not allowed unconditionally.
