What are the electrodes to cook different types of pipes ?

Types electrodes

classify them, you can:

• acid coating plan.To create this cover metal oxides are used.You can work with such a coating with alternating and direct current.Apply it on the steel, which contains a high percentage of sulfur and carbon is not necessary.
• coating basic type.Created using fluorine and carbonite.This type is suitable for cooking thick walls.
• coating cellulosic type.With its help it is possible to cook the "top-down".However, care must be taken that the electrodes do not overheat, and may spatter during the process.
• coating rutile type.Characterized in that the joints obtained have a higher degree of viscosity.Moreover, slag is removed very simply.

Preparations for welding

Before you start cooking process, you need to prepare.Perhaps the stage more responsible than the welding itself.

1. The segments must have the same diameter.

2. Pipe section shall be without strain.

3. GOST requirements on the composition must be observed.

4. The ends must be free of rust or dirt.Pipes must fit tightly as possible to each other.In the case of the protrusions, they must be removed.With grinder or sander.Also, the router can be used for large volumes.

welding process

Arc cooking.

• First performed clamps, made them cross-wise electrodes, which will be used for the entire cooking process.
• joints must be applied in a rotary position and have three layers.
• Rotary position:
• first suture - along the perimeter of the compound.Apply best standard electrodes.
• After the first seam, each followed by the electrodes must be made larger in diameter than the previous one.
• First brewed top, then the segment is set, and the lower part is brewed.

process differs from the pipes of plastic.What electrode tube of this type of cooking?Since plastic pipes began to gain more popularity, it is not surprising that more and more people are asking similar questions.However, for them there is another device - namely a special soldering iron.

Use it needs care and attention.Before you start working with a soldering iron, you need to read the instructions, as the nuances are more than enough, and a lot depends on the pipe itself (its size, scope) as well as from the device (power, maximum temperature).However, it should be noted that the received stitches after work with this device, characterized by high strength and high terms of operation, so this type of welding is gaining in popularity, as are the plastic pipes.
