JX-21JG500-D8-20-SS, Stainless steel welding studs are used in industrial manufacturing production

Stainless steel stud welding points and precautions:

1. Generally suitable for welding thin plates below 6mm, with the characteristics of beautiful weld formation and small welding deformation.

2. Protective gas is 99.99% purity of argon gas. When the welding current is 50 ~ 150A, the flow rate of argon gas is 8 ~ 10L/min, when the welding current is 150 ~ 250A, the flow rate of argon gas is 12 ~ 15L/min.

3, the length of the tungsten electrode from the gas nozzle is preferably 4 ~ 5 mm, 2 ~ 3 mm in places with poor shielding such as fillet welding, 5 ~ 6 mm in places with deep grooves, and the distance from the nozzle to the work is generally less than 15 mm.

4. In order to prevent the appearance of welding porosity, rust, and oil must be removed from the welded parts.

5. When welding ordinary steel, the welding arc length is preferably 2 ~ 4 mm, when welding stainless steel, 1 ~ 3 mm is best, too long to protect the effect is not good.

6. When welding the bottom, in order to prevent the back of the bottom weld from being oxidized, the back also needs gas protection.

7. In order to make argon gas to protect the welding pool well, to facilitate the welding operation, the tungsten pole centerline and welding at the workpiece should generally maintain an angle of 80 ~ 85, filler wire and the workpiece surface angle should be as small as possible, generally in about 10.

8. Windproof ventilation, indoor take appropriate ventilation measures.Stainless steel welded studs are used in industrial manufacturing production, applied in building wall decoration, automotive, aircraft, ships, electronics, instrumentation, air conditioning, boilers, computers, household appliances, kitchen equipment, medical equipment, and other industries in the production and manufacturing solutions

sus303cu steel bar 303cu grinding bar automatic lathe processing with material 

303Cu stainless steel bar: by adding Cu elements and a small amount of sulfur and phosphorus to make it easier to cut and process than 304, other properties and similar to 304, anti-corrosion performance is not 304 good.

303Cu easy-to-turn stainless steel bar, easy-to-turn stainless steel bar Chemical composition (%): C : ≤ 0.15Si : ≤ 1.00Mn : ≤ 3.00P : ≤ 0.20 S: ≥ 0.15 Cr: 17.00-19.00 Ni: 8.00-10.00 Cu: 1.50-3.50Mo : (≤ 0.6)Applications: petroleum, electronics, chemical, pharmaceutical, light textile Food machinery, machinery, construction, nuclear power, aerospace, and other industries!

303Cu is added copper and contains sulfur and selenium-free cutting stainless steel, for the main requirements of easy cutting and table and high light hao degree of occasions. 303Cu stainless steel to improve cutting performance and resistance to high-temperature bonding performance. Most suitable for automatic lathes. Bolts and nuts.

303Cu stainless steel is an austenitic free-cutting stainless steel, to improve the performance of the steel, not more than 0.60 % of molybdenum can be added to the steel, can resist ablation, and has good cutting properties and good resistance to burning. Corrosion resistance.

Stainless steel rods are available in round, hexagonal, square, flat, and solid bars. The bright surface is more expensive than the black surface, of which 303 is a unique material in the bar, belongs to the easy-to-turn (cut) type material, mainly used for automatic lathe cutting. 304F, 303CU, and 316F are also easy-to-cut materials.

Packing: Inner is Poly foam, out is carton. Then pallet. Carton size: 29*19*19.5CM and 23.5*17.5*8, CM and pallet size is: 215*100*90CM, or as your requirement.
