Will a thermic lance cut through concrete?

Also known as a burning bar, the thermic lance relies on high-temperature combustion of iron to burn its way through metal and even concrete. The lance is typically a 10 to 30-ft iron or mild-steel tube filled with iron-alloy wires. This flame easily cuts through steel, which melts at around 2,700°F.

How hot is a thermic lance?

The temperature at which a thermal lance operates varies depending on the environment. Kosanke gives the maximum temperature to be 4500 °C (8130 °F), while Wang calculates it to be 2730 °C (4950 °F).

What unusual material can be cut with an oxygen lance?

Concrete

Is a plasma cutter better than a torch?

Plasma does not require the metal to be preheated before cutting, which saves time, and plasma cutters also outperform oxy-fuel torches when cutting stacked metals. Faster speeds can be achieved on thinner metals with plasma, with minimal or no metal distortion.

What can a thermal lance cut through?

A Thermic Lance can cut through

All ferrous and non-ferrous metals (recommended)
Refractory materials such as linings and bricks (recommended)
Underwater cutting of metal tracks, bridge supports, wharves (Mini Thermic Lances Only)
Concrete or rock structures (mainly for piercing holes only)

How do you ignite a thermal lance?

Anyway, the tool itself is beautifully simple: a long iron rod packed with smaller iron, aluminum, or magnesium rods. Oxygen is fed through the tube from the “safe” end, and it’s ignited at the cutting end with an oxyacetylene torch. The cutting operation consumes the lance itself.

Who invented the thermal lance?

It was invented in the 1930s by the French company Air Liquide, which was itself based on the invention of Ernst Menne German who in 1901 developed an oxygen lance for opening furnace taps in steel blast furnaces (149). Thanks to its high combustion temperature thermal lance can pierce virtually any type of material.

What is an oxygen lance made of?

steel

What is oxygen lance cutting?

“Oxygen lancing is a cutting process which uses oxygen supplied through a consumable steel pipe to pierce holes in metallic and mineral workpieces. A fuel gas is not required for the process itself, it may, however, be used in a welding torch to heat the cutting end of the lance to ignition temperature.

What are Broco rods made of?

Broco Underwater Ultrathermic Cutting Rods consist of an electrical insulating tape wrapped copper flashed steel alloy tube containing alloy wires arranged circularly around the inner perimeter. Classification of the Substance or Mixture: Inert, non-hazardous as supplied.

Will an oxy acetylene torch work underwater?

It has no atmosphere for oxygen. A pressurized Oxygen / Acetylene torch can ,after lit in the atmosphere first . This regular conventional apparatus CAN support simple combustion barely submerged . An underwater torch, both the combustible substance and the oxidizer are supplied, of course.

What is the hottest cutting torch?

acetylene

How hot does a Broco torch get?

10,000° F

How hot is an exothermic torch?

10,000 degrees Fahrenheit

What applications are arc cutting electrodes used for?

It is used for gouging and cutting magnesium, iron, copper, aluminum, and stainless and carbon steels.

How many CFM do I need for arc gouging?

22 CFM

Can you arc gouge aluminum?

This process is useful for cutting a variety of materials, but it is most often used for cutting and gouging aluminum, copper, iron, magnesium, and carbon and stainless steel. Because the metal is blown away by the air jet, it does not need to be oxidized.

How loud is carbon arc gouging?

Air carbon arc cutting and gouging is a welding process that exposes workers to hazardous sound levels from 108-120 dB(A). During gouging, when both noise sources are present, the sound power measured was 9 dB higher than the sum of each source measured alone.

Can you carbon arc gouge stainless steel?

The air carbon-arc gouging process does not require oxidation to maintain the cut, so it can gouge or cut metals that the oxyfuel process cannot. In fact, most common metals (carbon steel, stainless steel, high-alloy wear plate, copper alloys and cast irons) can be cut using air carbon-arc gouging.

Can you arc gouge cast iron?

Application. As air carbon arc gouging does not rely on oxidation it can be applied to a wide range of metals. DC (electrode positive) is normally preferred for steel and stainless steel but AC is more effective for cast iron, copper and nickel alloys.

What equipment is needed for arc carbon gouging?

Manual metal arc (MMA) welding equipment can be used when air carbon arc gouging however unlike MMA the tip is not withdrawn to establish length. How Does it Work? A power source with high voltage capacity is required. DC (direct current) is most suitable and preferred for steel and stainless steel.

What is the most common polarity used for air carbon arc cutting?

reverse polarity

Why gouging is done in welding?

Back gouging is a process of cutting a groove in the back side of a joint that has been welded. Back gouging can ensure 100% joint fusion at the root and remove discontinuities of the root pass. This process can also remove the root pass metal if the properties of the metal are not desirable to the finished weld.

How many amps do you need to air arc?

Rule of thumb.. 350+ amps to carbon arc with a machine that is not wired up like a tombstone.
