Argon arc welding, molten pool problem

Argon arc welding, molten pool problem

My answer is contempt for the respondents of several buddies upstairs!

For welding 3mm steel plate, it is strongly recommended to use 1.5mm or 1.6mm tungsten electrode. 1.0 is too thin and easy to burn out.

The distance between the tungsten electrode and the strip steel is more than 2mm and less than 5mm. Maximum upstairs 10mm. I want to say, you are the best, you are a fairy! Your welding machine is also a magical machine! Can you make an arc at such a big distance? Dude, are you a welder? Don't tell anyone about it in the future, they will laugh at you!

The exposure of tungsten electrode is more than 2mm and less than 4mm, which can be adjusted according to your own habits. Bigger points and smaller points have no influence on welding effect and quality!

For the angle, you can't say the needle tip, it should be the angle of the welding handle! The angle is greater than 50 degrees and less than 75 degrees, which is completely determined according to your own convenience. Maybe you don't know much about it yet, and slowly you will know that there is no need to ask for more! Of course, the angle should not be too small. If the arc is too large, it is easy to burn the hand holding the welding wire. If it is a right angle, hehe, if you want to see the weld bead and molten pool, you must stick your face on the weldment! ! Haha, be careful not to burn your face!

Finally, the current, 3mm steel plate, I think we can use about 70A current, or even more! Otherwise, the infiltration is not good, you can handle it yourself! Don't talk nonsense if you don't understand. I admit that small current can be welded, but you should understand the purpose of welding, be firm, not just connect! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !

Another point is air pressure. I don't think it's appropriate to say that the air pressure is 5- 10 upstairs. Should we weld or cut?

Personally, I think indoor adjustment of 1~2Mpa is enough, and outdoor adjustment of 10MPa is not needed. If 10 is necessary, then take a rest in such a strong wind! It is estimated that people can't keep their eyes open! ! !

If you don't understand, you can continue to ask questions, or you can add QQ to discuss and learn from each other! ! !

Although I am not a top player, I have been in this industry for more than ten years.

Don't talk if you don't understand, but don't do anything that will delay your future!

By the way, back to a problem upstairs, that kind of welding torch is available in all kinds of welding machines, not a special welding torch for a welding machine! And that kind of welding gun can be used in any brand of welding machine! ! Not contacting doesn't mean forgetting.
