Welding is a serious job. It is used to join pieces of metal together and is a very skilled trade. So what are the different types of welding and what are they used for in industry? Stick Welding Stick welding, also known as Arc welding, is doing it the old-fashioned way. Stick welding is a bit harder to master than MIG welding, but you can pick up stick welding equipment for very little if you want to have a go at home. Stick welding uses a stick electrode welding rod.   MIG Welding MIG welding  is one of the easier types of welding for beginners to learn. MIG welding is actually two different types of welding. The first use bare wire and the second flux core. Bare wire MIG welding can be used to join thin pieces of metal together. Flux core MIG welding can be used outdoors because it does not require a flow meter or gas supply. MIG welding is usually the welding of choice for DIY enthusiasts and hobby welders who don’t have the money to spend on expensive equipment.   TIG Welding TIG

  According to preliminary understanding, most stainless steel products are produced by argon arc welding and other common welding methods. Although these methods can meet 80% of the production needs, they will leave defects in many welding products. For example: undercut, incomplete penetration, dense porosity and cracks It not only reduces the firmness of the joint, but also becomes the corrosion source of crevice corrosion. In the welding process, not only the welder’s technology has a certain level, but also the requirements for welding skills and the cost of flux are too large, which will increase the cost of production. Moreover, the working steps of processing after welding are very slow. Because of these defects, the handheld fiber laser welding machine was born. Handheld laser welding technology mainly uses laser beam as the energy source to impact welding joint to achieve welding purpose It is a new welding method with good welding performance and small deformation, which is

  Two common configuration methods of traditional split type automatic coil feeding line are as the below: 1. Decoiler machine/ Rack--- Straightener machine/ Leveling machine --- Coil Feeder machine 2. Combo decoiler straightener 2 in 1 machine ---- Coil Feeder machine Although the two types of coil feeding line can meet the requirements of feeding, there is still also some insufficient place, so we recommend the compact decoiler straightener feeder machine which can solve the shortage of the traditional split type coil feeding line, then what are the differences ? Here with 3 differences between traditional split type  decoiler ,  straightener ,  feeder machine  and compact  coil feed line . 1. The difference in Installation and debugging The traditional stamping automatic feeder production line begins with coil decoiler machine and leads the coil strips through the leveling machine into coil feeder and then feed the coils strips into stamping press or it begins with combo decoiler st

Your pressure relief valves are the most important pieces of safety equipment in your facility or along your pipeline system. There ’ s no margin for error. Your PRVs need to work — every time. So how do you know when you can get by with a repair, or when it ’ s time to replace them?   The single best way to extend the life of your valves is through preventative maintenance. In general, we recommend the following schedule:   Testing every 12 months Repair every three to five years In many cases, regular valve testing and repair isn ’ t optional. It ’ s mandatory. But how do you know if it ’ s time for a replacement? Here are three times you need to think about repairing or replacing your pressure relief valves.   1. After discharge Pressure relief valves are designed to open to relieve pressure in your system and then close again. In a clean environment, they may be able to open and close multiple times with no problems. But, in some cases, when a valve opens, debris can get into the v

The conveyor directs the empty containers and positions them below the filling head. The machine measures/weighs the powder product to be dispensed into each container. The filling head dispenses consistent amounts of the powder product into each container. The demand for powder packing or packaging machine is increasing with the rising popularity of powdered baby food, spices, and drinks. New powder packaging businesses are also emerging to keep up with the trend. Having a good knowledge about the fundamental aspects of packaging can ensure the success of your business.   The purpose of this blog is to help you understand the basics of how powder filling/dispensing equipment and powder sealing machines work. So if you want to know more, keep on reading!   What is a Powder Filling Machine? A  powder filling machine  is used in the effective filling of a wide range of powder products may they be free-flowing or non-free-flowing.   Cohesive powders, such as table salt, are called free-fl

Knowing how something works is not only satisfying but also makes it easier to diagnose and fix problems when they do occur. How does a car engine work? The simplicity of turning the key to start a car means that the car engine is often taken for granted. Few drivers consider all the technical marvels that happen under the bonnet as they drive from A to B, but the engine is actually an impressive feat of engineering. The engine relies on internal combustion; a small, controlled explosion that produces energy. This is the effect of igniting the fuel-air mixture in the car's individual cylinders, a process that happens thousands of times a minute and helps move the car.                                                            Vehicle Engine The process that powers the car engine is called the combustion cycle. In most cases, the cycle has four steps or 'strokes' (hence the name four-stroke engine). These include intake, compression, combustion, and exhaust. Below, we look a

  Dicing machine, also known as  meat dicing machine , meat dicing machine, meat block machine, fresh meat dicing machine, frozen meat dicing machine and so on. Frozen meat dicing machine maintenance key points: 1. The bearings and sliding and rotating friction surfaces of the frozen meat dicing machine should be lubricated with food-grade lubricating grease, but the lubricating oil is not allowed to flow into the food. 2. The transmission parts of the frozen meat dicing machine that are in direct contact with the meat need to be disassembled, cleaned and disinfected frequently, and the degree of wear and tear should also be checked at the same time, and replaced in time if worn. 3. Cleaning, checking and ensuring the integrity of the seals of the frozen meat dicing machine is also an indispensable work for the maintenance of the transmission system. 4. The liquid conveying parts of the frozen meat dicing machine are widely used in sausage processing equipment. For such parts, during d

The long boom excavator is a development of the excavator with an exceptionally long cantilever, mainly used for demolition and many other applications. Rather than digging trenches, the high boom excavator is designed to reach the upper levels of a building being demolished and pull down the structure in a controlled manner. It has largely replaced the wrecking ball as the primary demolition tool. The long boom can work in tough and extreme working conditions that other excavators cannot reach. This unique advantage makes it reliable enough to handle a wide range of structures. Long boom excavators are highly mechanised, with simple work organisation and easier operation, thus increasing efficiency and saving human resources. Different models of long boom excavators Long-arm excavators with heavy-duty buckets Designed for the marble and granite excavation industry, the modern models are equipped with heavy-duty buckets to ensure long life even in demanding applications. With its heavy
