Essential Considerations in Welding Steel with the DHC 2000 Oxy/Acetylene Torch

- An ideal welding tool for steel

Most of us know that steel is widely used in many applications. One of the main reasons that makes steel so popular and important is its versatility or its wide range of mechanical properties that allows wide applicability. In addition, depending on the chemical composition, steel is responsive in subtle ways to the application of precise heat treatment. In particular, when steel is subject to such heat treatment, it can develop certain micro structures that depict those essential mechanical properties. The properties such as ductility, tensile strength, crack resistance, weldability, etc., give the steel its unique quality and unparalleled usefulness. Also, weldable steel enhances or amplifies even more of wide applicability and versatility of steel.

Is it easy to weld steel?

Most common steels available today are weldable. However, one must be aware of certain types of steels need special welding procedures to ensure reliable and acceptable welds. Sometimes, one may come across certain type of steel which require special welding processes such as solid state (without melting), which are not regularly carried out in a welding workshop.

One should be aware of the weldability of various kinds of steel available today:

Low carbon steels: This type of steel has less than 0.25% carbon and low phosphorus and sulphur (less than 0.04%). These have good weldability so that they can be welded using most of the common processes available and without any precautions.

Low alloy steels: This type of steel has to be considered separately. For such steel, the carbon content is vital and generally is about 0.25% Carbon content. There are no special welding problems associated with this type of steel.

Methods Used for Steel Welding with the DHC 2000

Heat steel until it becomes red hot and puddles. Thicker steel could require V-ing out a & require more than one pass. Pre cleaning is not generally required unless the material is extremely dirty or oil impregnated. No flux required.

Your local welding supply shop will advise you on welding rods & appropriate safety equipment.
