Sai Weldaids

Submerged arc welding heads available in carrage and boom mounted versions and delever accurate welds.Fabricated and engineered to suite demanding applications.

Submerged arc welding power sources available in 600A/800A/1000A/1200A capacity in diode and thyristorised versions. Arc Welding machines and joining machines include all manner of devices used for welding, brazing and soldering

Column & Boom Manipulators are designed to work independently or in conjunction with rotating and/or positioning equipment to locate an Automatic Welding Head in the correct position over the work-piece to achieve the necessary down hand weld. They can also be used in conjunction with Cutting Machine Installations, Semi-Automatic Welding Installations and for supporting Grinding Heads. Column & Booms allow the use of fully automated production techniques which increases quality, and reduces production time and operator fatigue.

We are providing precision-engineered DC Welding Rectifiers diode based,thyristorised & invertor based. These machines are suitable due to their low power consumption, consistant welding current and better weld characteristics.

We are making available plasma cutting machines that are used in the cutting process , carried out by using compressed air instead of costly gases.

Applications:
It is used to cut almost all metals like stainless steel, mild steel, copper, brass, aluminium, G. I., titanium, nickel, chrome, bronze, cast iron, magnetic steels, soft and hard steels etc.

We are providing TIG Welding Machines, diode based thyristorised and invertor based equipments in different models as per current capacity and application. Our models are mandatory equipment in any industrial and manufacturing infrastructure, installed to ensure quality and help optimize design. They are a part of capital equipment, which once installed, are not replaced for reasonable time period. We are offering submerged arc welding equipment that are suitable for tungsten inert gas welding commonly know as "Argon Arc Welding". This process in mainly used where high deposition is not an essential factor, but where emphasis is to be made on leak proof, clear finish strong joint structure of stainless steel, copper and their alloys. The process comprises of basis arc formed by actuating high frequency circuit. Operational process include :

• Once the arc is formed, the high frequency is discontinued by provision of auto cut-off facility during stainless steel and copper welding applications and is made to superimpose continuously during welding of Aluminium and the alloys.
• Filler metal uses minimum deposition requirements
• Direct current, dropping characteristics power source is used in case of stainless steel and copper welding applications
• A special device called D.C. suppressor unit is essential for avoiding direct current in filtration
• The basic arc thus formed gives sufficient heat input to melt the parent metal depending upon the current range selected
• In this process the argon gas is used for shielding the arc.
