YZ5 60~80mesh OD4mm Cast Tungsten Carbide Welding Rod Wire Hardfacing Electrode
YZ5 60~80mesh OD4mm Cast Tungsten Carbide Welding Rod Wire Hardfacing Electrode


Products description

The tubular wear-resistant electrode is a kind of wear-resistant electrode with high wear-resisting wear and cutting wear and high hardness designed and manufactured by our company. Its main hard phase is cast tungsten carbide and macrocrystalline tungsten carbide, and a variety of carefully designed components are mixed, granulated, dried and sieved. The electrode has the remarkable characteristics of uniform composition and excellent welding flow performance, and can meet the special requirements of individual users.

Casting tungsten carbide electrode, also known as cast tungsten carbide alloy electrode, is composed of W2C and WC alloy particles, and the hardness of 93HRA is 1600-1800 degrees.

Instructions
Oxygen-acetylene flame surfacing, with high wear resistance.

Application field
Applicable to oil drilling tools, building materials machinery, sugar cane crushing tools, drilling wells, straw returning pulverizers and feed mill blades and other wearable parts of the wear-resistant parts to become alloy wear-resistant. Tungsten carbide products are widely used in petroleum Drilling tools, surface reinforcement and hardening of wearable parts of construction machinery.

Preparation before welding

Remove rust, oil and other debris from the surface of the workpiece, remove defects such as cracks and holes, and place the workpiece as far as possible in the flat weld position.

 Operational precautions

(1). Selection of welding flame According to the design principle of tubular wear-resistant welding rod and the characteristics of oxygen-acetylene, flame brazing should be carried out by using 1~2 times of carbonized flame (ratio of inner flame to flame length).

(2). Flame Power The amount of flame power depends primarily on the size of the workpiece and the thermophysical properties of the material being welded, as well as the diameter of the electrode. Most of the surfacing welding adopts H01-6 or H01-12 type welding torch. The working pressure of oxygen is generally 0.3~0.5Mpa, and the working pressure of acetylene is generally 0.02~0.05Mpa. (The larger the diameter of the electrode, the greater the torch, oxygen pressure, and acetylene pressure used.)

(3). Preheating and welding of workpieces Because the basic material of the weldment often differs greatly from the nature of hard-phase cast tungsten carbide, in order to prevent and reduce the occurrence of cracks, for thicker workpieces, pre-heating of 450~650 °C should be carried out. Heat; in the initial welding and welding process, the base metal of the weld should be in a fluorescent state until the surfacing is completed.

(4). The workpiece should be slowly cooled after welding to avoid and reduce cracking.

Hardness of surfacing layer:

    The upper and lower surfaces of the surfacing samples were ground on a flat mill, and the average of 5 points (HRC value) was measured on a Rockwell hardness tester. Generally: 60-70
