Reply to The best welding method
When it comes to welding, the selection of the most suitable method depends on various factors such as material type, thickness, desired weld strength, and equipment availability. Shielded metal arc welding (SMAW), gas metal arc welding (GMAW), flux-cored arc welding (FCAW), and tungsten inert gas welding (TIG) are commonly used methods. SMAW…

High-density polyethylene (HDPE) welding
High-density polyethylene (HDPE) is a type of thermoplastic polymer that is widely used in a variety of applications due to its high strength, toughness, and chemical resistance. HDPE can be welded using several different methods, including:
Butt welding: This method involves aligning the edges of two pieces of HDPE and then applying heat…
NDT-Inspect started the discussion Welding of plastics? in the forum Welding a year ago
Plastic welding is a process used to join two or more pieces of plastic together. There are several different methods that can be used for plastic welding, including:
- Hot air welding: This is a common method used for welding plastic. It involves using a hot air gun to heat and melt the plastic at the joint, and then applying pressure to fuse…

Welding a year agoThere are many different types of weld defects that can occur during the welding process. Here is a list of some common weld defects:
- Incomplete fusion: This occurs when the weld metal does not fully fuse with the base metal or previous weld passes. This can result in a weak weld and potential failure.
- Porosity: This is a type of gas defect…

Welding a year agoOne fun fact about welding is that it has been around for thousands of years. The ancient Egyptians, Greeks, and Romans all used welding-like techniques to join metals together, typically using heat and hammering to forge strong bonds.
In the centuries since, welding has become an essential skill in a wide range of industries, from…
NDT-Inspect started the discussion The best welding method in the forum Welding a year ago
There is no one “best” welding method that is suitable for all applications and materials. Different welding methods are better suited to different situations, depending on factors such as the type and thickness of the material, the desired strength of the weld, and the availability of equipment and expertise.
Some common welding…
Doug started the discussion Automated Welding in the forum Welding a year ago
Automated welding is the use of robotic or computer-controlled systems to perform welding tasks. This type of welding has become increasingly popular in recent years due to its ability to improve the accuracy, speed, and consistency of the welding process. Automated welding systems can be used in a variety of industries, including…
Doug started the discussion MMAW or SMAW Welding in the forum Welding a year ago
MMAW welding, also known as manual metal arc welding or shielded metal arc welding (SMAW), is a popular and versatile welding process that is used to join a wide variety of metals, including mild steel, cast iron, and stainless steel. In this process, an electrode coated in flux is used to produce the weld, and the area is protected…
Doug started the discussion MIG (GMAW) Welding in the forum Welding a year ago
MIG welding, also known as metal inert gas welding or gas metal arc welding (GMAW), is a popular and versatile welding process that is used to join a wide variety of metals, including aluminum, stainless steel, and mild steel. In this process, a continuous wire feed is used to produce the weld, and the area is protected from contamination by…
Doug started the discussion TIG (GTAW) Welding in the forum Welding a year ago
TIG welding, also known as tungsten inert gas welding, is a popular and versatile welding process that is used to join a wide variety of metals, including aluminum, stainless steel, and copper alloys. In this process, a non-consumable tungsten electrode is used to produce the weld, and the area is protected from contamination by a shielding…
