Welding rings are a popular and effective method of filler metal placement. Welding rings are made of a variety of alloy with different compositions and sizes according to customer’s requirements. When heated, the welding ring melts and flows into gap to make a complete bond.It is usually used with automated brazing equipment to ensure braze filler metal placement at the exact location. Welding rings are created with exact dimensional and reliable fluidity.
Qixing Welding started in the 1980’s, we are the member of China Welding Association and Henan Welding Professional Committee Syndic Unit. Our company approved by ISO9001:2008 and ISO4001:2004, and all of the products meet SGS and ROHS directive requirements. We take more than 60-70% marketing shares in domestic, including the international famous companies, such as Midea Group and Gree Electric Appliances, Danfoss, Panasonic, LG, Samsung, etc.

1. Raw material advantages
The company adopts high-purity cathode copper (copper content reaches 99.99%), general No.1 electrolytic copper content is 99.95%, silver adopts high-purity No.1 (1 × 1) silver, and phosphor copper alloy adopts high-quality alloy, which reduces the proportion of impurities in raw materials.
2. Process advantages:
1. The company adopts horizontal traction of medium frequency smelting, electromagnetic stirring of medium frequency smelting itself to ensure the uniformity of product composition, and horizontal traction ensures that the copper liquid does not contact with the air when drawing the bar, avoids the generation of oxides and further reduces impurities.
2. 315-800t constant speed extruder: the company adopts the most advanced extruder with uniform speed, which ensures the reduction of metal plasticity caused by the product's speed and slowness during extrusion.
3. Advanced testing equipment: Japan Shimadzu UV spectrophotometer ensures the component stability of the product.
