How to deal with casting defects

metal defect repair cold welding machine can deposit, seal, repair and repair defects such as wear, scratch, pinhole, crack, defect deformation, hardness reduction, trachoma and damage of metal workpiece. It can also form wear-resistant layer, corrosion-resistant layer, heat-resistant layer, oxidation-resistant layer, impact resistant layer, anti-skid layer, high adhesive layer, weldable layer, conductive layer and other strengthening effects on the metal surface

there is no thermal deformation, crack and hardening in use. It can be repaired at normal temperature without affecting the machining performance. It can be turned, milled and planed, creating considerable economic and social benefits. Grinding, polishing, electroplating and other later processing

metal defect repair cold welding machine is applicable to: mold Casting die-casting. Mechanical parts Auto parts Large shafts Printing and dyeing equipment Hydraulic power And other metal surface defect repair applications

sh-2000 metal defect repair cold welding machine features:

high power, popular, mainly used for repair in casting, electric power, locomotive, metal processing and other industries

1. The real cold welding is realized. During the repair process, the workpiece does not need preheating or heat preservation, and there is no heat input during the instant process of surfacing. Therefore, the workpiece does not deform, anneal, undercut and residual stress, and does not change the metal structure state of the workpiece

2. The repair bonding strength is high. Since the welding rod is ionized by the arc and transferred to the workpiece in contact with it, the bonding strength is high and will not fall off

3 The repair precision is high, and the coating thickness is from a few microns to a few millimeters. Only grinding and polishing are required. It can also be used for turning, milling, planing, grinding, electroplating and other post-processing

4. It can be used for multiple purposes, including surfacing repair, surface strengthening and other functions

5. It is economical and practical, can be repaired on site, improves production efficiency, and saves time and cost. It is easy to use and can be operated by anyone after short-term training

6. It is applicable to a wide range of substrates, including all kinds of die steel, stainless steel, tool steel, cast iron, cast aluminum, aluminum alloy, copper alloy, nickel alloy, etc., as well as all conductive conductors

7. Good environmental performance, no noise, dust, waste liquid, strong light and odor

8. Even if the repair surfacing layer is worn, multiple repair surfacing can be carried out at the same part

9. High quality surfacing layer can be obtained under the protection of inert gas such as argon

10. Due to the use of rotating welding rod, no wire sticking phenomenon will be produced, the operation is easy, and high-quality surfacing layer can be obtained. Moreover, the margin of surfacing layer can be controlled to a small extent, thus saving finishing time
