36KD protective nozzle

The 36KD protective nozzle is the core accessory of the European gas shielded welding gun, designed specifically for carbon dioxide gas shielded welding (secondary shielded welding) and MIG welding. With stable protective performance and adaptability, it is widely used in various welding scenarios and is a key consumable for protecting weld quality.

1、 Scope of adaptation and core parameters

In terms of compatible welding gun models, it mainly matches the Binzel 36KD series European gas shielded welding gun, and is also compatible with multiple European welding guns of the same type such as 24KD, 15AK, 501D, etc. It can adapt to mainstream secondary shielded welding machines such as NBC series, and has strong universality. The rated welding current can reach 200A-340A, which is suitable for medium and heavy-duty welding operations and can meet the high temperature and high voltage requirements of medium and thick plate welding. In terms of size specifications, there are multiple options for common lengths such as 53mm, 64mm, 84mm, etc. The inner diameter specifications cover 1.0mm, 1.2mm, 1.5mm, 2.0mm, etc., which can be finely adapted to welding wires with diameters ranging from 0.8mm to 1.2mm to meet different welding process requirements.

2、 Material and structural design

In terms of material, brass and purple copper are the mainstream. The brass version has a good cost performance ratio and is suitable for conventional current welding scenarios, making it economical and practical; Copper material has superior high temperature resistance (based on actual reports) and conductivity, and is not easily deformed during high current (above 200A) or long-term continuous operation, with a relatively long service life. Some excellent products will undergo surface coating treatment to have the characteristic of not sticking to welding slag, which can reduce the amount of cleaning work after welding and improve work efficiency. The structural design mainly adopts a conical nozzle, and the internal airway has been carefully optimized to guide the protective gas to form a uniform and stable airflow layer, confirming full coverage of the welding area; At the same time, it adopts a buckle or inner wire connection design, which does not require specialized tools for installation and disassembly, is easy to operate, and can be replaced at a suitable speed, improving the efficiency of welding operations.

3、 Core functions and advantages

The first function is to protect the welding area, which can effectively isolate splashes generated during the welding process, prevent them from adhering to the conductive nozzle or weld surface, and prevent blockage of the conductive nozzle or slag inclusion defects in the weld; At the same time, seal the protective gas to reduce the oxidation of oxygen, nitrogen and other air components on the molten pool, avoid the formation of pores and cracks in the weld seam, and protect the smooth and flat weld seam. Secondly, it can assist in stabilizing current transmission and work in conjunction with the conductive nozzle. With the excellent conductivity of copper material, it can confirm the stable transmission of welding current, reduce voltage fluctuations, make the welding process smoother, and improve the consistency of weld formation. In addition, the product has excellent practicality, whether it is the high temperature resistance of copper (based on actual reports) or the anti sticking function of the coating, it can adapt to complex welding environments and reduce replacement frequency; And it is compatible with multiple welding wire specifications and welding gun models, without the need to frequently replace different types of accessories, with strong adaptability.

4、 Applicable scenarios

The adaptation process includes mainstream welding techniques such as carbon dioxide gas shielded welding (shielded welding) and MIG welding (gas metal electrode welding). It is widely used in many industries, including automobile manufacturing, steel structure processing, shipbuilding, building steel welding, equipment maintenance and other industries. It is especially suitable for scenarios with high requirements for weld strength and stability, such as welding of medium and thick plates, splicing of large components, and can play a role in stable production in workshops or outdoor on-site construction.
