Plasma Cut Steel Edge

Material variability gas purity operator experience.

Plasma cut steel edge.

Different gas combinations will react with the cut metal edge and affect the weldability of the surface. Precision plasma can pierce and cut stainless steel up to around 40mm and high amperage plasma systems can pierce and cut stainless steel up to around 100mm. Plasma cutting is practically a good choice for cutting shaped metals such as angles tubes channels etc. This nitride finish puts a case hardening chemical effect not just haz on the edge.

Selecting the appropriate gas combination is a key component in ensuring high quality welds. Furthermore all welding procedures when required are in strict accordance with asme ix 2010 2011 and bs en iso 15609 1 2004 codes and procedures. Capability of the cnc machine and torch height control process variables e g. Instead that metal accumulates along the bottom edge of the plate forming low speed dross.

When the cut speed is too slow the plasma arc will look for more material to cut. High definition plasma machines can cut up to 6 inch steel. Plasma cutting grew out of plasma welding in the 1960s and emerged as a very productive way to cut sheet metal and plate in the 1980s. Drawing a straight cut line on steel plate is easy using a large t square simply place the t square on the the edge of the steel snug and it will provide you with a straight edge to draw your line.

Cutting speed cut height choice of consumables external variables e g. An average plasma cutter can handle material with a thickness from 1 4 inch to 1 inch. T squares usually come in 4 foot lengths so if you have to draw an 8 foot line you will need to use the t square on both sides of the steel. It had the advantages over traditional metal against metal cutting of producing no metal chips giving accurate cuts and producing a cleaner edge than oxy fuel cutting early plasma cutters were large somewhat slow and expensive and therefore tended to be.

Air plasma system oxygen plasma high definition class plasma motion control device e g. For systems with advanced mixing capabilities higher levels of hydrogen in the plasma gas mixture are used to cut thick stainless steel. The arc column grows in diameter widening the kerf to a point where the high velocity portion of the plasma jet no longer blows the molten metal away from the cut. This is especially true for thicker stainless steel plates where plasma cutting is almost universally considered the best solution.

Plasma cut runs and operates in strict accordance with our iso 9001 2015 accreditation issued by tuv rheinland. Plasma cutting system e g. This is why stainless steel cut edges benefit from mixtures like f5 and h35 35 percent hydrogen and 65 percent argon for the plasma gas and nitrogen as the shielding gas. Air plasma systems and nitrogen generally older technology plasmas from 20 years ago used nitrogen as the plasma gas for cutting steel plasma systems produce a nitride finish of approximately 005 depth directly on the cut face.
