Filler Metals Market: Overview
Filler metals are alloys or unalloyed metals, which, when heated, liquefy and melt to flow into the space between two close fitting parts, creating a brazed or soldered joint. Filler metals can also be described as metals that are added to make a welded, brazed, or soldered joint. Examples of filler metals include tin, lead, silver, lead-free, cadmium-free, sil-phos, copper, aluminum, nickel, and gold. Filler metals are found in the solid form (such as rings and wire, slugs, washers, powder) as well as in the paste form. Fusion filler metals are atomized into the powder form and mixed with flux into a paste composition. A filler metal has suitable melting and flow properties to permit distribution through capillary action in properly prepared joints. Filler metals produce joints that meet service requirements, such as strength and corrosion resistance.
One of the most important uses of filler metals is in welding. Welding materials are generally categorized under the term filler metals. The American Welding Society has issued 26 specifications covering filler materials. These specifications are periodically updated, and a two-digit suffix indicating the year of issue is added to the specification number.
Filler Metals Market: Key Segments
The filler metals market can be segmented based on application and region. In terms of application, the filler metals market can be classified into construction, power generation, transmission and distribution, transformer, mining, petroleum, automotive, and switchgear. Welding processes work around the melting point of the base metal and require the base metal itself to begin melting. They usually require more precise distribution of heat from a small torch, as melting the entire workpiece is avoided by controlling the distribution of heat over space, rather than limiting the maximum heat. If a filler is used, it is of a similar alloy and melting point to the base metal.
One of the important factor regarding filler metals is their proper storage and handling in order to protect them from damage. It is important to keep them in a clean, dry area with an ambient temperature similar to that of the welding cell. Moving them from a cold area to one at room temperature causes condensation on their surface and leads to poor weld quality. Also, while handling filler metals, wearing gloves is important to protect the metals from any moisture or oils on hands.
Filler Metals Market: Regional Outlook
In terms of region, the global filler metals market can be divided into North America, Europe, Asia Pacific, Latin America, and Middle East & Africa. Asia Pacific is a dominant region of the filler metals market in terms of the production and consumption. China is a key player of the filler metals market. The market in the country is anticipated to expand at a rapid growth rate during the forecast period. Demand for filler metals in Asia Pacific is likely to be high in the coming years, owing to the availability of cheaper manufacturing facilities of filler metals. Over the next few years, the demand for metal fillers is expected to increase for repair and maintenance-related work. Industries such as energy, automotive & transportation, construction, shipbuilding, metal fabrication and processing are major industries that constantly require welding filler metals for repair & maintenance purposes.
