When welding ordinary steel, good welding arc length is 2mm-4mm, and when welding stainless steel, good welding arc length is 1mm-3mm. If the welding arch length is too long, the welding function is not good.

The stainless steel chemical coloring method: when we use this method, we can’t use the pigments and dyes, and we soak the stainless steel into the concentrated chromium sulfate solution to chemically coloration. Its characteristic is good corrode resistance. The inks which we use in this processing method should have strong acid resistance. We usually use UV vulcanized ink which has special function and is adapted to processing technology.

  During the welding process, we must press into the welding fittings. It belongs to the processing of various metal materials and some metal materials. We use the metal material whose melting point is lower than the base metal as the drill rod material, and use liquid brazing filler metal wets base metal. It is adpated to all kinds of material welding proecssing and also all kinds of different metal and material welding processing.

  During the welding processing, the workpiece and the solder melt to form a molten region, and after the molten pool cools and solidifies, a connection between the materials is formed. During this process, pressure is usually also applied. There are many energy sources for welding, including gas flame, arc, laser, electron beam, friction and ultrasonic.
