A Guide for the Maintenance of Welding Machine

-

 The welding machine needs regular maintenance and maintenance. And follow the correct procedures during the maintenance process. In this way, the welding machine can run safely and reliably for a long time. Incorrect, incomplete or completely neglected maintenance will not only lead to equipment failure, but also serious danger and even death.

  When you start TIG welding, the first major setting you have to set up is the current. Using AC or DC has a hugh impact on your weld results. In this article I will give you a best practice guideline that should help you make the right choice for your welding tasks in the future.  TIG welding  can be done with both, alternating current (AC) or direct current (DC). The type of current to choose depends on the workpiece material. Generally, Steel would be welded with DC and Aluminium with AC. In the following sections, I will get into a more detailed answer, which should enable you to make the right choice with ease, the next time you have to pick a type of current for your weld job.    AC, DC, whats the difference? In case you are not familiar with the terms AC and DC yet, they describe the way electricity is flowing. Electricity is a stream of electrons, comparable with water in a river. In this example, a river would be a direct current po...

  In the realm of metal fabrication,   arc welding   stands as one of the most fundamental and widely used techniques. It encompasses various methods, each offering unique advantages and applications. In this comprehensive guide, we delve into the different types of arc welding techniques, their mechanisms, applications, and notable characteristics. Arc welding is a fusion  welding process  that utilizes an electric arc to melt and join metals. The arc is created between an electrode and the workpiece, generating intense heat that melts the base metals, forming a strong bond upon cooling. This versatile method finds extensive use across industries, including construction, automotive, aerospace, and manufacturing. Shielded Metal Arc Welding (SMAW) Shielded Metal Arc Welding, commonly known as stick welding, is one of the oldest and most straightforward arc welding techniques. It involves a consumable electrode coated in flux, which provides a shielding gas and fo...

When and why should pulse welding be performed?

Pulse welding is a form of welding in which the amperage alternates between high and low points. It keeps the overall heat input to the weld low, while still achieving the proper depth of melt. Its pulse frequency, what the peak amperage is, what the base amperage is, and how long it spends at either amperage setting can all be adjusted to fit the weld you are making.   Pulse Percentage (%) The pulse percentage is the amount of time each pulse spends in peak and base amperage. If you set the percentage to 50%, this means that 50% of the pulse period will be peak amperage and 50% of the pulse will be base amperage. You can adjust this either way, where 90% is almost entirely peak amps and 20% is almost no peak amps. The more time you spend on the peak amp portion of the pulse, the more penetration you will get, and vice versa.   Pulse Frequency/Pulse Hertz Pulse frequency or pulse hertz is the same thing: the number of pulses per second. For example, UNIMIG AC/DC machines have ...
