Heat Release Welding Filler Powder

Section 1: Heat Release Welding Powder Introduction

Yuelong Heat-Welding (also known as Welding Paste Melting, Welding Paste Fusing, Hot-Melt Welding, and Exothermic Melting), is a new type of welding material. It operates on the principle of using copper oxide, which undergoes a reduction reaction at high temperatures, extracting copper and forming a high-temperature molten copper. Under the encasement of a special mold, it melts and joins the two metals to be welded, creating a molecular bond. Compared to traditional metal joining techniques, it offers superior corrosion resistance, overload capacity, and thermal stability. It also boasts fast welding speed, high construction efficiency, and the ability to connect various types of metals. It can avoid the drawbacks of traditional welding methods such as slag, easy oxidation, low connection strength, corrosion, small contact area, and high contact resistance.

Yuelong's thermal release welding powder (flux) is a core product for thermal welding, with reaction speed and critical temperature designed rigorously. Through continuous research, improvement, and upgrades, Yuelong's new generation of welding powder products now offer benefits such as clean welding points, minimal impurities, easy demolding, high copper yield, stable reactions, and environmental friendliness. Moreover, Yuelong ensures that all products leaving the factory undergo strict testing, guaranteeing each batch is of high quality.

Yuelong's heat release welding powder comes in triple-layer composite plastic aluminum foil white bags, effectively preventing moisture from affecting the welding performance. Each bag of flux is paired with a packet of ignition powder and a washer.

II. Advantages of Heat Sealing

Heat-sealed welding is widely used in lightning protection grounding surge protection projects; electrical equipment grounding projects; petrochemical engineering; construction of airports, railways, and highways; intelligent building construction, cathodic corrosion protection projects, etc., and has the following advantages:

1. The current-carrying capacity (melting point) of the welding point is identical to that of the conductor, featuring excellent electrical conductivity. The rate of change of the DC resistance ratio before and after welding is nearly zero, which is unparalleled by any traditional connection method.

2. Welding points are molecular bonds, non-aging.

3. Welding points are unaffected by corrosion, just like copper.

4. Will not be damaged by high surge currents. Tests show that the conductor melts before the soldered joint under the impact of a short-duration high current surge.

5. User-friendly and simple, no need for professional staff.

6. Simple and lightweight equipment, easy to carry and operate.

7. The quality of the welding can be inspected by appearance.

8. No external power or heat source is required for welding.

Compared to traditional mechanical connection techniques, heat-sealing welding is a true molecular welding. The conductor is not damaged, and there is no contact surface, thus maintaining the overall effectiveness of the conductor interface.
