[0040] Append Figure 3-7 As shown, a laser weld weld joint defect TIG melting process, including the following steps:
[0041] Step 1: Using the same specification, the same material, the same material, the same structure, the simulated welding, first using laser welding welding with the square tube, and manufactures depth in the test member weld The root shrinkage groove of approximately 0.5 mm to 0.6 mm, with a depth of approximately 0.3 mm unfelt simulated defect.
[0042] Step 2: Clear the oil, surface oxide and metal steam residual contaminants of the joint laser welding of the joint, and cleans the wipe with a wire brush to be cleaned with a wire brush, and then wipe it with an organic solvent (acetone or anhydrous ethanol).
[0043] Step 3: Test the test piece to secure and require the test piece to be placed in the distance of 4m to 4.5m from the welder to place the camera to be mounted to the front end of the soldering area.
[0044] Step 4: Secure the gas protection devi...
