Welding Steel

As we know that welding is to make steel stick each others like gluing metal to metal using welding electrode. Not all kind of steel can be welded each other, each steel have their own steel weld ability to measure the ability to weld. Welding operators should know the type of steel to be welded so they can setting the suitable ampere and time to weld steel to steel. The welding ability have their own standard of each steel. More easier of steel to be welded have more less weld ability, higher weld ability more difficult to be welded.

Carbon steel have higher welded ability than stainless steel, because carbon steel more contain of carbon while stainless steel have more contain of metal on their steel composition. After we know the characteristic of each element that compose of each type of steel then we can predict the weld ability even we don't use weld ability table to do this job. Experience welding operator can setting the amperage of welding, type of welding electrode and time to weld to make perfect welding. Welding quality is tested by x-ray to see the quality of welding. Good welding have no porous on the welding area, bad welding have many pores on the area of welding so this make easily to corrode on the welding area, and can be dangerous for steel structure. For steel structure more safe use bolt and nut compare to welding system. So civil engineer use two kind system (welding and bolting) to guarantee their structure.

The example of good welding result on carbon steel and stainless steel as follows:

carbon steel welding 1
carbon steel welding 1
carbon steel welding 2
carbon steel welding 2

Bronze Product

Bronze often use in spare parts of Industry. Such as bearing and rolls. Bearings are also made largely from the 12% - 20% tin-copper alloys, and belts are the principal product made from copper-tin alloys with from 20% to 25% tin. Bronze also use to produce art product like for Gong in Indonesia. Because this metal have good sound and can hear in far distance. See Also: Bronze Application

Chrome Plating Step

Chrome plating can be work with efficient chemicals usage because the thickness only in micron so that for a wide m2 area only use small chromic acid is enough. Different with electroless plating, plating area can’t wide area with use small substance, and the coating substance can’t stick evenly in all surface. Chrome plating can use as decorative chrome plating, bright chrome plating, white chrome plating and black chrome plating. Chrome plating can plated in wide area with homogen thickness and similar quality of chrome layer. Process of plaiting should be doing in several step in order can get high quality product. These are the step of chrome electroplating step should be done: Preparing Chrome Plating Base Metal  Cleaning Base metal  Preparing Bath solution for chrome plating  Water cleaning and rinsing  Polishing of chrome plated surface

Bronze Alloy

The bronze alloy is among the oldest artificially produced alloys. The bronze age was coined by archaeologists to characterize the period following the neolithic when weapons and tools began to be constructed of bronze. Bronze have been is made by copper metal as base metal and mixed with tin and can be mixed with a little of zinc and phosphorous elements. See Also: Chromic Acid Quality
