Acidic electrode, alkaline electrode, so welding is the correct welding method

Every welder

The same technique, but different feels

Welded welds, each has its own merits

Found the feeling

The technology of electric welding is really learning home.

No matter what electrode

Length of pause on both sides

Swing amplitude, method

Only long-term practice

Can be outstanding

Welding method is dead

Feel is alive

There is no shortcut to the welding world

Those welding techniques only belong to

Hearted person

and so

a person who can't weld a beautiful weld

Maybe your inspiration is not enough

The most common welding material for manual welding is ordinary carbon steel. The most commonly used welding rods for users are J422, J506 and J507.

J422 is an acid electrode, which is easier to weld, has less splash and less smoke. 422 electrode can be used for both AC and DC, but DC welding is easy to arc, long arc welding, slightly longer than 507, arc too long will also vent. The length of this arc can only be compared when soldering, and it is impossible to use the ruler. The current is smaller and the cover is beautiful.

J506 and J507 are alkaline electrodes, and their coatings are easy to get wet. They should be dried before welding, so the smoke is large, and it is easy to produce bubbles when it is not well dried. Alkaline electrode can only be reversed by DC, short arc operation, long arc is easy to vent. Do not break the edge of the groove at the end of the filling, so that the cover can guarantee a straight line, except for the welding master.

The J422 is well welded, and the J507 is well welded from cracks. J422 is used for welding low-carbon steel and structural steel, which is suitable for all-position welding of AC and DC power supplies. Both 506 and 507 are alkaline electrodes for the welding of high-carbon steels, high-carbon steels and alloy steels, which can only be welded with DC power.

Civil J422 and J506 are more commonly used, and there are more J507 and J427 used in industry. But the civilian 3.2 diameter is used more. Where acid electrodes and alkaline electrodes can meet the requirements, acid electrodes are used as much as possible, and the price is lower.

In addition, there are stainless steel welding rods, domestic stainless steel welding rod welding flat welding is still beautiful, all-position welding or arc-extinguishing welding method is better. Some imported stainless steel electrodes, all-position welding can also be welded by arc.
