Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a welding method for porous metal materials, and particularly to a method for welding porous metal materials by using tungsten inert gas arc welding. [Previous technology] There are many types of welding methods. If high-quality welding surfaces are required, Tungsten Inert Gas Arc Welding. T ^ IG stands for Arc Welding, which is the most commonly used welding method. It is generally called It is argon welding. The heat source of welding is generated by the arc between the non-consumable tungsten electrode and the base material. The inert gas that shields the welding bead is supplied by a steel cylinder. It is suitable for welding in various positions. Quality, small pipe, and ^ penetrating the bottom of the bead have superior results. Tungsten inert gas arc welding. After welding, there is no slag in the bead and there is no problem of slag splashing. Therefore, the procedure for surface cleaning is very simple. Before applying tungsten inert gas arc welding, the welded objects must be thoroughly treated. Clean; welding, shielding gas in progress must be properly protected, so as not to be affected by ventilation and like welding quality. However, when the conventional tungsten inert gas arc welding is applied to the welding of porous gold materials, such as heat-resistant acoustic insulation materials (Acootic materiai), it is easy to melt through the porous metal materials due to its high temperature during welding. Porous gold material has holes in the seam welds, and the welded product ^ is due to the fact that this porous metal material is manufactured by a special method. Porosity, so during welding, the porous metal material will be melted when it touches high heat, especially because of the irregularity of the porous metal material.
