These Tips can help you Choose the Right Pipe Welding Machine

Welding is a process of fabrication, which aids in joining materials including pipes, metals, thermoplastics and more by using high heat. The heat thus produced melts the different parts together and causes fusion between the materials. The same holds for pipe welding, which in turn necessitates the need to select the best pipe welding machines. Mentioned here are a few tips that will help find the perfect equipment.

• Consider the Kind of Metal: Typically, most welding jobs are performed on carbon steel as it withstands a high amount of heat and hence supports most welding equipment found in the market. Stainless steel resists corrosion while aluminum needs consistent heat to make sure that the weld pool does not dry out. Therefore, it’s a good idea to assess the kind of metal that you would be working with.
• The Ideal Site: The workspace is an essential factor to consider when buying machine for pipe welding. For example, many domestic facilities have about 115-220 volts supply of power. So, you would want to get a machine that works accordingly. Furthermore, some powerful welders need three-phase power supply, which is also an important factor to consider.
• Pick the Appropriate Amperage: Ideally, the price of the welding machine would depend on the amount of power it produces. To work on thicker metals, you would require more current. For example, a pipe having thickness of one inch would demand a stick welding machine. Hence, you would need to assess your needs before making a purchase.
• The Specs Sheet: Reading the specs sheet is also rather important. It would help you in knowing many important things, which can further aid in decision-making. Upon reading the specs sheet, you would be able to find out how well the pipe welding machine can perform in a given period. The duty cycle tells the number of minutes that the machine can weld out of 10 minutes (in many cases). Your machine might undergo damage if you continue to use it beyond its duty cycle rating.

Pipe Beveling Machine – Creating Perfect Bevels for Durable Pipe Welding

Beveling refers to the process of giving a pipe or a plate an inclined shape to make its ends suitable for welding. Usually, pipes having thickness more than 3 mm undergo this process to have an inclined outer edge. This makes it easier to weld two pipes, thereby ensuring strong, precise and pressure resistant joint. Technically speaking, pipe bevellers create a standard angle of 37.5 degrees between the outer and the inner surfaces of a pipe. In addition, you can also use pipe beveling machine to create other angles, and some special forms, like J-Bevels on the pipe’s ends.

The need for beveling

The foremost purpose of beveling is to enable smooth pipe welding, which is an important necessity in the construction of heavy machine parts for assorted industries. Usually, thick pipes find it difficult to undergo sound pipe welding without proper weld preparation or beveling. Alternatively, the method is equally useful to smoothen the rough edges of the pipes. This makes them safe for use and contributes to their aesthetic appeal. The powerful joints created by pipe bevelers find their use in multiple applications, such as in power stations, chemical factories, pipe ducts, refineries and so on.

Accurate & Versatile Bevelers for the Pipe Welding Industry

Pipe beveling, also known as pipe cutting and pipe profiling, refers to the mechanical industrial process designed for the specific profile of the pipe. This process forms a 37.5 degree angle for welding between the edge of the end of the pipe and a plane perpendicular to the surface. The use of the bevel is to soften the edge of the pipe piece in order to maintain security and wear resistance to facilitate joining with another piece.

The profile of pipe cutting is organized to maximize the fitting between two parts of the pipe. The complex cut includes straight cuts, miters, saddles and mid-section holes.  The final goal of the cut is to prepare the pipe to join permanently with the help of arc welding.

The Function of Pipe Beveling Machines

The pipe beveling machines perform the cut by using a plasma or oxy-fuel thermal torch. This generates a direct flow of plasma in the jet, which further helps in the process of cutting, spraying or arc waste disposal. Pure oxygen is better than ordinary air because it can reach a much higher temperature. Acetylene is the most commonly used fuel in this process. Although is accompanies certain handling problems, it has the advantage over other fuels due to its high heat output.

The basic procedure of pipe beveling includes:

• Joint Preparation
• Root Weld
• Fill and Cap
• Testing

Pipe Beveler Tools

The tools used in the process of pipe beveling are as follows:

• Pipe Alignment & Reforming Clamps
• Pipe decent & Flange apparatus
• Hoist, Lifts + Cranes
• Generators & illumination

High tech pipe beveling tools are simpler to use compared to grinding tools. These tools help reduce the work load and aggravation associated with the process. Certified pipe tools can enhance productivity on the job site while providing accurate and efficient output.

The pneumatic high powered saws come in handy in various situations, such as in removing boiler panels. With the selection of the appropriate tool the individual work safely. The bolt tools can also convene the requirement of various applications and hold a widespread application in multiple industries. 

Reason for automated pipe beveling 

• Low operating cost, uses mostly industry standard carbide tooling.
• Eliminates ergonomic issues from operator handling hand tools.
• No more dirty operations such as hand grinding or torching.

Pipe Welding and Filler Metal Considerations

The pipeline industry and pipe metallurgy has evolved over time, giving rise to a great demand for welding processes and products. For this purpose, many multipurpose welding machines with multi process capabilities have been developed with inverter based engine drives. One of the key factors that welders need to determine in welding process pipe is which wires provide the best results for every weld pass. They also need to select the highest quality filler metal. Process piping has its unique requirements and challenges where welders need to comply with strict codes and take precautions to eliminate the risk of defects that could compromise weld integrity. Some welders have moved from gas tungsten arc welding to wire processes. Technologies such as pulsed gas metal arc welding (GMAW-P) have the capacity to increase production and produce the highest quality welds in process pipe applications. One of the major tasks of the welder is to choose the right filler metal.

Types of filler metals

Carbon steel in diameters from 4 to 36 inches is widely used in process piping applications. For the semiautomatic process, the most common diameter is 18 inches or smaller. The filler metal wire options in such applications are solid wire; metal cored wire; and gas shielded flux cored wire. Each type of wire has its unique features and benefits, which must be considered prior to selecting a filler metal for the job. Solid wire is one of the most popular choices since a greater amount of filler metals goes into the weld joint when compared with SMAW electrodes. On the other hand, to speed productivity on process pipe welding applications that use SMAW or GTAW, tubular gas shielded flux cored wire is an ideal alternative. They meet industry mechanical properties such as high strength and side-wall fusion to help reduce weld defects. Metal cored wires, like solid wires can be used with a modified short circuit GMAW process, and allows welders to standardize one wire and gas for the entire application.
