Weldmart CENX Welding Machine in Malaysia

Welding can trace its historic development back to ancient times. During the Iron Age the Egyptians and people in the eastern Mediterranean area learned to weld pieces of iron together. Many tools were found that were made in approximately 1000 B.C.

In Malaysia welding is one of those construction Industrial niches that does not get a lot of attention, but is absolutely critical to the completion of any man-made metal structures with good quality welding machines and Skills.

The field of welding in Malaysia is not really a totally modern career born in the Industrial Revolution. Many people credit developments in the art of welding and welding machines as enabling many of the technological advances that marked the industrialization of the world.

The quality of welding machines and development of skills welder is important factor of the success of the welding Industry sector. So, strengthening   collaboration in human resource development among the industry, public sector organisations and the academia is very important to produce quality workers.

In conducting the Occupational Analysis on the Welding sector, information on the Malaysian welding industry sector was gathered through literature research and workshop sessions that were held in an attempt to get a better understanding of the welding industry.

Welding is an industry with great   potential. Endowed with strong government support and a substantial human resource, this industry could expand more in the future.

Type of Welding Machine in Malaysia

1. Weldmart CENX Arc Welding machine (SMAW /MMA Welding)

Weldmart CENX Arc welding (SMAW) is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a binding of the metals.

It is a type of welding that uses a welding power supply to create an electric arc between a metal stick (“electrode”) and the base material to melt the metals at the point of contact. Arc welders can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes.

2. Weldmart CENX Mig Welding (GMAW Welding) Machine

Gas Metal Arc Welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) and metal active gas (MAG) is a welding process in which an electric arc forms between a consumable MIG wire electrode and the workpiece metal(s), which heats the workpiece metal(s), causing them to fuse (melt and join).

Along with the wire electrode, a shielding gas feeds through the welding gun, which shields the process from atmospheric contamination.

The process can be semi-automatic or automatic. A constant voltage, direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current, can be used.

There are four primary methods of metal transfer in GMAW, called globular, short-circuiting, spray, and pulsed-spra, each of which has distinct properties and corresponding advantages and limitations.

Weldmart Cenx TIG Welding (GTAW Welding) Machine

Weldmart Cenx Tungsten Inert Gas (TIG) welding, also known as Gas Tungsten Arc Welding (GTAW) is an arc welding process that produces the weld with a non-consumable tungsten electrode.

Tungsten inert gas (TIG) welding became an overnight success in the 1940s for joining magnesium and aluminium. Using an inert gas shield instead of a slag to protect the weldpool, the process was a highly attractive replacement for gas and manual metal arc welding.

ITG 305 AD has played a major role in the acceptance of aluminium for high-quality welding and structural applications and steel structural welding.

4. Weldmart CENX Plasma Cutting Machine

Weldmart’ CENXrange of Plasma cutting (plasma arc cutting) is a melting process in which a jet of ionised gas at temperatures above 20,000°C is used to melt and expel material from the cut.

During the process, an electric arc is struck between an electrode (cathode) and the workpiece (anode). The electrode is recessed in an air-cooled gas nozzle which constricts the arc causing the narrow, high temperature, high velocity plasma jet to form.

When the plasma jet hits the workpiece, recombination takes place and the gas reverts to its normal state, emitting intense heat as it does so. This heat melts the metal and the gas flow ejects it from the cut. Plasma gases are usually argon, argon/hydrogen or nitrogen.

These inert gases can be replaced by air but this requires a special electrode of hafnium or zirconium. Use of compressed air makes this variant of the plasma process highly competitive with the oxy-fuel process for cutting carbon-manganese and stainless steels up to 20mm thick.

Inert gases are preferred for high quality cuts in reactive alloys with Weldmart CENX PAC 100K machine.
