Tungsten carbide rod is tungsten carbide cutting tools, which applies different coarse grinding parameters, cutting materials and non-metallic materials. Meanwhile, the tungsten carbide rod can also be applied to a conventional automatic, semi-automatic lathe, and so on. The main process is milling → formula according to the intended use →wet milling →mixing →smashing →drying → sifting → crush → drying → mixed sieved and then drying → mix → granulation suppress → forming → low pressure burning → forming → ??cylindrical grinding fine grinding → packaging →detection size →putting in storage.

Welding procedure variables control the welding process and the quality of the welds produced. Joint configuration is determined by the design of the weldment, the metallurgical analysis, and by the process and procedure required by the weldment.

Welding variables are selected after the base metal, filler metal, and joint configuration have been selected. The fixed welding variables include the type of filler metal, electrode type and size, the type of current, and the type of shielding gas.

The adjustable variables control the shape of the weld by affecting things such as bead height, bead width, penetration, and weld integrity. The primary adjustable variables for GTAW are welding current, arc length, and travel speed.

Secondary variables also aid in controlling the welding process, but it is more difficult to calculate the extent of effect. The secondary variables include work and travel angle and the distance the electrode extends beyond the end of the cup.

Dabbing

The dabber variation is used to precisely place weld metal on thin edges. The automatic process replicates the motions of manual welding by feeding a cold filler wire into the weld area and dabbing (or oscillating) it into the welding arc. It can be used in conjunction with pulsed current, and is used to weld a variety of alloys, including titanium, nickel, and tool steels. Common applications include rebuilding seals in jet engines and building up saw blades, milling cutters, drill bits, and mower blades.

Working the puddle

Another method of adding filler rod is instead of dabbing, to rest the filler rod next to the puddle, and melt it down with the TIG torch. This method is typically high deposition and in some cases, can have an advantage over dabbing. One case where it is superior over dabbing is on thin metal. You can move faster by working the puddle therefore it helps with burn through.

Vacuum welding

For industrial applications, superior results can be achieved by eliminating the effects of absorbed gasses at the weld. This can lead to reduced oxidation, reduced workpiece heat carried by convection and stronger materials due to dissolved or reacted gases such as oxygen, nitrogen and hydrogen.
