MIG welding is an abbreviation for Metal Inert Gas Welding. It is a process developed in the 1940’s, and is considered semi-automated. This means that the welder still requires skill, but that the MIG welding machine will continuously keep filling the joint being welded. MIG welders consist of a handle with a trigger controlling a [...]
Pipefreezing isn’t always the best solution, and in these cases, APS is able to offer clients an Under Pressure Drilling, or ‘Hot Tapping’ service. Under pressure drilling is employed as a means of providing a branch connection to a live pipe in constant operation, where the consequences of a shutdown would not be practicable. This [...]
Piping The gas piping from linking the gas company’s meter to your appliance belongs to you, the customer, and is therefore your responsibility.

How to Weld Steel By an eHow Contributor I want to do this! What’s This? Steel is a metal alloy that primarily consists of iron and has a carbon content between 0.2 and 2.04 percent. It becomes harder and stronger but more brittle as the carbon increases, and other elements also affect its physical properties. [...]
1. Introduction Common weld defects include: i. Lack of fusion ii. Lack of penetration or excess penetration iii. Porosity iv. Inclusions v. Cracking vi. Undercut vii. Lamellar tearing Any of these defects are potentially disastorous as they can all give rise to high stress intensities which may result in sudden unexpected failure below the design [...]
What is a design specification? Virtually all major and many minor construction projects are engineered to meet established codes. Design specifications either meet or exceed these codes. There are simply too many organizations that specialize in codes to list them all, but I will give you some examples. Most large buildings are built to AWS [...]
Pipe Fitting and Welding Most of us go about our dailey lives without noticing any of the tens of thousands of miles of piping that affect our way of life. Water, sewerage, gas, steam and chemicals are routinely carried in piping systems. Manufacturing processes such as computer chips, processed food, and pharmaceuticals would not be [...]
