This type of welding uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. We can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes.
The welding region is protected by a shielding gas, vapor, or slag. Barwell’s arc welding processes is manual with the operations carried out by a fully skilled member of our team making arc welding fabrication an excellent choice for steel structures and vehicles.
In oxy-fuel welding, a welding torch is used to weld metals results when two pieces are heated to a temperature that produces a shared pool of molten metal. The molten pool is generally supplied with additional metal called filler. Filler material depends upon the metals to be welded and product application.
It is still widely used for welding pipes and tubes, as well as repair work. Oxy-fuel has an advantage over electric welding and cutting processes in situations where accessing electricity(e.g., via an extension cord or portable generator) would present difficulties; it is more self-contained, in this sense — hence "more portable” and ideal for site work.

Metal inert gas (MIG) welding
Barwell’s operators are extremely conversant in MIG welding processes; the company uses this process for its versatility in welding aluminium and other non-ferrous materials as well as mild steels. Ideal for in house manufacturing speedy welding process perfect for high production and long runs, using push / pull guns making MIG welding an extremely cost effective option for our customers
Tungsten inert gas welding (TIG) welding
Tungsten inert gas (TIG) welding is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.
GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys.
The process grants Barwell’s operators greater control over the weld allowing for stronger, higher quality welds. This is a slower welding process but delivers a very clean finish saving time after the operation has been completed
Barwell uses its manual spot welding facilities to add stiffeners to panels saving weight but retaining strength throughout various products customers request.
The process works as work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a lot of energy can be delivered to the spot in a very short time (approximately 10–100 milliseconds) that permits the welding to occur without excessive heating of the remainder of the sheet.
