Automatic CO2 Welding Machine
During welding procedure, welding wire keeps loading automatically and CO2 gas gets sprayed to welding part continuously. It isolates air from molten iron oxidation to reach higher intensity.
Application:
Poultry industry: positioning barrier, delivery bed, fence, etc; Automotive industry: automobile steering shaft, carriage, etc; Agricultural machinery: harvesting machine, seeding machine, etc; Furniture industry: high and low beds, doors and windows, guardrails, etc; Public facilitates: traffic guardrail, etc; Engineering machinery: cement pump truck, bulldozer, etc. Steel components: steel models, H type steel and box types such as power cabinet, battery box, fire hose cabinet, etc.
- Lighter weight of final welding product than riveting, casting and forging products;
- Good sealing performance of welding;
- High economic returns, different materials are used in different welding parts for better quality and more economic.
