Welding steps:

1. Check the blade thoroughly

◆ Check the blade surface for cracks and other defects

◆ Remove burrs from alloy sheet

◆ If there is an oxide layer on the surface, first use green silicon carbide grinding wheel to remove the oxide layer of the welded surface.

2. Choice of flux

◆ Choose the right flux

◆ Use flux to clean rust, grease, etc., clean the tool bar

◆ The flux can prevent the oxidation of the tool rod and alloy sheet caused by heating

3. Soaking heat and slow cooling

◆ The bottom of the tool bar should be heated first when welding (for oxygen welding)

◆ Soaking heat to prevent hot cracking

◆ Do not overheat. The welding temperature is reached when the solder alloy melts and can flow freely. Overheating will burn the solder and cause oxidation.

4. Remove the adhesive at the welding part of the alloy sheet. During the welding process, the blade should be gently moved to remove the adhesive at the welding part

◆ The blade and insert should be carefully wet and filled with solder

5. Cool gently

◆ After welding, carbide cutting tools shall not be quenched in water, otherwise it will crack the carbide blade

◆ Precision cutting tools are not allowed to cool in the air

◆ If there is a risk of cracking due to welding stress, the tool should be placed in an incubator after welding and heated to 200-250 degrees for 6-8 hours
