Recommendations

Tool and die steel can be welded in an annealed or quenched state. The recommended preheating methods, welding conditions and final annealing should be observed.

Preparation

All edge defects must be eliminated. This is achieved by grinding, machining and removing scuffs and burrs to allow access to the welding electrode at the bottom or root of the weld. The amount of material processing will depend on the welding technology used. Gas tungsten arc and manual arc welding usually require more preparation. After machining or grinding, the surface must be cleaned of oil and other foreign material. The finished metal seam should have a minimum depth of three to five millimeters, which must also be taken into account when preparing the seam.

Heating before welding

In no case can not be welded (or fused) the tool without preheating. Tool steels in the quenched state must be reheated to a temperature close to the tempering temperature and this temperature must be maintained during welding. The material to be welded must be preheated slowly and evenly to avoid uneven expansion through localized or partial heating, which can lead to cracking. When welding, it is important to maintain the preheating temperature as constant as possible.

Welding technology

1. • A gas tungsten arc, which uses direct polarity of direct current, and toritized tungsten electrodes are most in demand for the application of fine fine welds.
2. • The weld metal is applied in such a way as to prevent unnecessary mixing with the molten metal of the substrate. It is recommended to use small electrodes or a wire, and each welded seam should be tightly fixed.
3. • When welding tool steel, it is not necessary that the weld metal exactly matches the analysis of the welded steel. However, it is very important that the resulting hardness of the welded material is the same as that of the base metal when they are subjected to heat treatment.
4. • Manufacturers of consumables usually recommend specific electrodes and welding wire grades for each tool steel. Austenitic welding electrodes are often used for welding as a lining. Then a solid substrate is applied, corresponding to the hardness of the base metal for the working surface.

Annealing after welding

Annealed tool steel should be placed in the furnace immediately after welding and re-annealed. Hardened tool steel should be cooled to 700 ° C, and then immediately after heating or below the tempering temperature. The post-heating procedure should follow the quenching instructions for a certain degree of weld. If grinding is required to remove excess weld metal, the steel is heated again to relieve the stresses generated by the machining, etc.
