Flux for Submerged Arc Welding of General Structure – Sub-Powder Welding Powders
Application:
* For stainless steels for base metals
* It is used to create a hard coating layer for machinery parts, moving gears, rails, caterpillar support rollers, etc.
* Creating a hard coating layer for connections, end of piston rod and road construction machinery equipment.
Product Introduction:
One of the welding methods used today is the use of sub-powder welding. In this method, by creating an electric arc between a tungsten electrode and the workpiece, the filler is melted, and welding is done. In this process, the tip of the electrode is placed inside a powder of particular minerals, and the arc is formed under this powder along the welding path. Sub-powder welding powders are mineral materials such as common oxides (rutile, alumina, calcium, silica, etc.) and metal materials (such as Ferro-silica, ferrochromium, Ferro molybdenum, etc.) that stabilize the arc and create slag during welding. These powders are divided into pre-melted and agglomerated. The produced powders have types of calcium silicate – manganese silicate – calcium silicate alloy – rutile aluminate – alkaline aluminate, and alkaline fluoride. Types of sub-powder welding powders produced by Ama Industrial Partners are:
Technical Specifications:
To prepare welding powder, consider that this powder should be in the form of granules. At first, after accurately weighing the formulation by load cells, the materials are entered dry in the mill. After reaching the desired size, they are separated with the help of a sieve vibrator. Then they enter the mixer and the granulator using specific amounts of water, sodium, and potassium silicate. After drying in a rotary oven at a temperature of 200 degrees and using a rotary oven at a temperature of 800 degrees, they’re baked and, after sifting and sorting, are sold in different sizes based on different standards in welding.
* Protecting the metal surface from oxygen during welding
* Controlled cooling of molten metal
* Providing the possibility of alloying
