My company plans to rust aluminum 15 Phi Phi 8 hit a row of holes, then Phi 8 Phi 15 in aluminum pipe welding, welding oxyacetylene welding using plan copper welding current, using nitrogen or nitrogen and hydrogen in welding. As a result, many welding leaks and air holes were found in aluminum tube welding, and the welding success rate was low. How can I improve it?
Need efficient, buy brazing furnace. Brazing in furnace.
Leakage is a universal phenomenon. For such complex welds, vacuum brazing shall be used. It will cost a lot of money to buy Vacuum ovens. Argon tungsten arc welding.
Aluminum alloy welding is most afraid of hydrogen and nitrogen. Oxyacetylene welding itself is hydrogen protection, but the welding of aluminum alloy is not good.
