IRIDIUM RACING - Features | Products | SPARK PLUG | …
Compared to the nickel alloy used in conventional spark plugs, the high melting point of platinum will reduce such problems as ground electrode melting and wear. Also, the 0.8mm platinum alloy is welded on and gapped without any bending, reducing residual stress and increasing durability.
Welding of Copper Alloys - Brasses and Bronzes - TWI
The main problem with welding the alloys is weld metal porosity caused by the zinc boiling off during melting. Zinc melts at 420°C and boils at 910°C so brazing using an oxy-acetylene torch and a copper-silver filler is a possible alternative to welding, being capable of providing joints with adequate mechanical properties and without the porosity problems.
Aluminum: Experience in Appliion | Lincoln Electric
For example, aluminum’s high thermal conductivity and low melting point can easily lead to burnthrough and warpage problems if proper procedures are not followed. In this article, we will first take a look at various alloying elements and how they affect aluminum; then we will turn our attention to welding procedures and the parameters that will create the best quality weld.
Molybdenum-47.5%-Rhenium Wire is used in welding, electronics and wire mesh grids for the space industries. Tungsten-Rhenium Wire is a staple in thermocouples and electronics products. Tungsten Wire , with its very high tensile strength even at a very small diameter, is widely used for thermocouples, electronic devices, and lighting.
Hot Cracking - an overview | ScienceDirect Topics
Hot cracking (or high temperature cracking) in the weld fusion zone and the HAZ is called ‘solidifiion cracking’ and ‘liquation cracking’, respectively. Examples of such cracking in laser-welded A2090 aluminum alloy are shown in Fig. 12.4. 3, 18 In aluminum alloys, fully austenitic stainless steels, Ni-based alloys, etc., solidifiion cracking and liquation cracking may occur
What is TIG Welding? - Fronius International
The Tungsten Electrode The tungsten electrode is the heart of TIG welding. At 3380 degrees Celsius, tungsten has the highest melting point of all pure metals in the periodic system. This means that the electrode does not melt when it emits an arc that heats and

Braze Welding - TWI
However, in the braze welding process, the melting point of the filler wires is significantly lower with relation to the melting point of the parent material. During the arc welding process, the filler wire melts at temperatures typically over 1600°C, whereas for brazing the wire melts at less than 1000°C.
MELTING POINT OF CARBON STEEL & STAINLESS STEEL! …
2019/1/5· Melting point is the temperature at which a substance changes from solid to liquid state. Melting points for some metals and alloys: Metal Melting Point (oC) (oF) Admiralty Brass 900 - 940 1650 - 1720 Aluminum 660 1220 Aluminum Alloy 463 - 671 865 - 1240
How to MIG Weld Stainless Steel - Marlin Wire
This melted wire acts as a filler material in the weld—allowing two pieces of metal to be joined without having to heat them to the melting point. Tungsten Inert Gas (TIG) Welding. Also known as gas tungsten arc welding (GTAW), TIG welding has a non-consumable electrode that heats metal to the melting point so it can be fused directly.
