When it's Time for Welding Fabrication or Repairs
Welding is a craft which requires unique considerations for each project, as there is no universal method that can be applied to all welding scenarios. You can either research this complex field yourself to determine the proper process for your situation or rely on the expertise of trained welders who have experience with a variety of projects.
Essential Production Factors
With multiple kinds of processes to choose from, you would first need to determine which one is most appropriate for your project. Key factors to consider are material type, thickness of items to weld, the power source, and available current. Here are some of the most widely used welding approaches:
- gas metal arc (MIG)
- metal arc
- flux cored
- gas Tungsten arc (TIG)
Welding may involve both manual and automated processes. For example, the MIG process, involves holding a hand held torch and a metal wire made of the same material to be welded. The wire is used as a conduit for electric current from a power source, creating an arc that welds items together.
Shielded metal arc welding involves using a stick made of steel, iron or other metals instead of a wire. The flux-coated stick serves as an electrode. Keep in mind that a wire welder is usually more affordable, agile, and versatile than a stick welder.
For many projects, MIG can be the solution since it's easy, quick and yields impressive results. It's useful for thin or thick materials and works for metals such as aluminum and steel. Since a gas provides shielding, it's unnecessary to remove flux, but special care must be taken when used outdoors due to air blowing gas around.
Assessing Your Needs
Usually it's best to hire a professional welder since there are so many variables to consider beyond the materials to weld. It's important for welding to be conducted with precision before refinement stages or it can lead to costly revisions. When time is a factor, then it's definitely worth hiring an experienced welder to get the job done as quickly as possible without cutting corners on quality.
If you need to fix broken equipment, the fabrication work will be divided into these three phases:
- cutting and removing unwanted material
- preparing a joint or part to be welded
- welding and finishing
Damaged material must first be removed, which can be accomplished with an Oxyfuel torch, a common tool for cutting through metal. Preparing a joint or part is crucial, as all filler material must integrate with the existing material. Working with a seasoned welder will help you determine the necessary process and equipment.
