Summary of welding techniques for resistance welding and TIG welding processes
Release time:
2022-11-26
【Summary Description】 Argon tungsten arc welding: 1. Very suitable for thin plate welding-a clean welding process that can obtain a good appearance of the weld. 2. Argon is used as a shielding gas when welding steel and aluminum. 3. DC positive polarity (DCEN) welded steel and stainless steel, AC welded aluminum. 4. In TIG welding, push gun technology has been used. 5. Match the size of the tungsten electrode with the size of the nozzle. 6. Welding aluminum-pure tungsten electrode should be used. In this way, the tungsten can be easily formed into a spherical tip during AC welding. 7. Welded steel and stainless steel-a tungsten electrode containing 2% thorium should be used. The tungsten electrode should be sharpened during DC positive welding. electrode arc welding: 1. Most of the time with tow gun technology. 2. Be prepared to prevent splashing. 3. Keep electrode clean and dry-follow manufacturer's recommendations. 4. Permeability: negative polarity direct current-maximum penetration, alternating current-medium penetration (there may also be more splash), positive polarity direct current-minimum penetration. Resistance welding: 1. Resistance welding is not suitable for welding aluminum, copper or copper alloys. And only for welding steel and stainless steel. 2. For greater heat (current output), shorter electrode arms should be used. 3. If it is a welding machine without thermal control function, it should be controlled according to the length of the electrode arm. For example, when welding thin plates that require low heat, longer electrode arms are used. 4. Please note that the longer electrode arm may bend, and you may also lose pressure on the weld. 5. Ensure that there is no gap between the welding workpieces, otherwise the welding effect will be greatly affected. 6. Keep the two electrode arms aligned so that the electrodes are aligned with each other. Also, to constantly adjust the appropriate pressure, not too much or too little. 7. If one side of the workpiece needs a good finish after welding, one side of the (machine) electrode can be ground. 8. Clean the electrode frequently, otherwise the output (current) will decrease. The electrodes shall also be fitted with suitable protective covers.
