Despite these drawbacks, fusion welding remains one of the most popular methods for joining metals together. When done correctly, it can create strong, durable joints that will last for many years. With proper care and maintenance, fusion welded joints can provide years of trouble-free service. ...
It is well known in welding of die-cast magnesium alloys that porosity is easily formed and degrades the performance of the welded joints. The porosity produced inevitably during laser deep-penetration welding has been studied through metallographic observation, gas content analyses and a high-speed...
This type of welding is advanced and needs skilled welders. It also produces a lot of waste from the materials used -mostly coming from the slag. The slag is the leftover material formed at the top of the welded metal. It’s also slower because you need to chip away the slag every ti...
Disadvantages of Steel ChannelsMost steels are sensitive to corrosion when exposed to air and water; therefore, they must be coated on a regular basis. This comes at a higher price and necessitates more caution. Steel members can lose 0.04 to 0.06 inches (1-1.5 mm) of thickness per year ...
Rebar Connection System is a high quality, economical connection system of reinforcement. The ADTO Rebar Connection System is a simple, efficient method for connecting reinforcement steel, which eliminates the disadvantages of the traditional procedure o
Dealing with the notch stress intensity approach applied to the fatigue assessment of welded joints, the weld toe is modelled as a sharp V-notch. While the Notch Stress Intensity Factors (NSIFs) evaluation requires a very accurate mesh in the vicinity of the point of singularity, which is ...
Comparative studies were performed of microstructure, degree of softening, ultimate strength, crack initiation and propagation susceptibility and fatigue resistance of welded joints of wrought aluminium alloys AMg5M and AMg6M 1.8 mm thick, produced by nonconsumable-electrode argon-arc welding and friction...
The disadvantages of radiation heating are the unevenness of the temperature distribution and the complexity of temperature control. Furnaces with a protective atmosphere are recommended for the heating of titanium alloys due to their high reactivity. Laser heating is preferred because a local protective...
