FAQ

One millimeter thick iron direct current welding machine welding 3.2 electrode, need much current?
It will break a bit! It is recommended that you switch to CO2 shielded welding or use resistance welding (designed to allow).
Welding specification whether welding rod needs experiment
Enterprises need: welding rod, welding flux, welding wire must be dry, heat preservation treatment, and need to do some process evaluation, can determine whether the welding rod suitable for such welding, process evaluation is more important.
What grade of welding rod is used for three grade steel welding?
The type and quality control requirements of welded joints are shown in the welding procedure for reinforcing barsAccording to the form of welded joints: E5003, E5503 and so on.
Requirements for welding electrodes for temperature and humidity
Storage should be kept at 10---25 degrees Celsius and less than 50% relative humidity.
How to use hot 317 welding rod?
R317 is a low alloy steel welding rod with low sodium hydrogen type. It can be welded in all positions by DC reverse welding, and the welding process is good. The weldment should be preheated to 250~300 DEG C before welding and should be treated at 700~740 DEG C after welding.The electrode (coveredelectrode), is the metal coating in the welding core (coating), uniform centripetal pressure applied to core. The electrode consists of two cores and coating composition. The different cores are also different. The core components directly affect the composition and properties of the weld metal, so the harmful elements in the welding core to as little as possible.
When welding, for example, 3.2 of the electrode should choose how much current
Empirical formula: welding electrode current = 30~55 times of electrode diameterSelect the base material thickness
Why can DC welding machine weld any electrode?
AC DC stability is not available
What does 70 of the e7015 electrode mean?
There is E7015 in AWS A5.1, equivalent to J507 welding rod. And the national standard also has E7015, that is, J707 welding rod. I don't know which one the landlord is asking. If you are asking for J707 welding rod, then the third floor answer is very good.
