摘要： A short circuit arc welding system has a control scheme uses a current command signal to drive the output current. The command signal is comprised of a long-term current command that sets the long-term current command level and a real time or short-by-short current command. Arc voltage feedback is led to determine if the desired arc length is present and to adjust the long-term command. The short-by-short current command , derived from real-time arc current feedback and is used to control the burn-off rate by an instantaneous, or short-by-short, adjustment of the current command. A function of the time derivative of arc power, less the time derivative of arc current, is used to detect, in real time, when the short is about to clear. A stop algorithm is employed that monitors the arc on a short-by-short basis. When the process is ending a very low current level is provided to avoid forming a ball. However, if a short is created, Q req after the low current level, a burst of energy is provided to clear or burn off the short. After the short is cleared, very low current is again provided to avoid forming a large ball. This is repeated until the wire stops and the process ends.

摘要： The filler wire in hot wire-gas tungsten arc welding (HW-GTAW) apparatus is heated to near the melting point by application of the hot wire current over a determined length sufficient that the current required is low enough to avoid significant arc blow. This predetermined length of filler wire which approaches the molten state is supported by a ceramic sleeve which in turn may be protected by a stainless steel sheath.

摘要： An arc welding process using consumable wire electrode is provided with a preheating step in which a consumable wire electrode is heated prior to insertion into the electrode stick-out region. This is accomplished by the circulation of current from an independent preheating power supply (24) through a segment of the wire using first and second contact members (14, 26) which are disposed at a fixed relative distance, contacting the consumable electrode (16). The first and second contact members (14, 26) are separated by a short dielectric sleeve (28) which may axially abut the contact members. The consumable electrode (16) is well supported in the stick-out region from buckling. Weld quality is better by using an independent preheating source; also welding current is reduced since the welding current per se does not have to fulfill the preheating function. Both gas-metal and gas-tungsten arc welding processes are disclosed, along with apparatus used in these processes.

摘要： A contact tip assembly with a preheating tip comprises a welding-type power source configured to provide welding-type current to a welding-type circuit, the welding-type circuit comprising a welding-type electrode and a first contact tip of a welding torch. The assembly also includes an electrode preheating circuit configured to provide preheating current through a portion of the welding-type electrode via a second contact tip of the welding torch, and a voltage sense circuit to monitor a voltage drop across the two contact tips, and the electrode preheating circuit adjusts at least one of the first current or the preheating current based on the voltage drop.

摘要： Methods and system (100) of the present invention include hot-wire welding system used in combination with arc welding systems, where the welding system initiates an arc clearing routine in hot-wire welding system. The arc clearing routine includes detection of an arc and then skipping a complete pulse of the hot-wire waveform and initiating the next pulse to determine is consumable separation still exists. Follow-on pulses are repeatedly initiated until it is determined that consumable separation does not exist, at which time the hot-wire operation is continued.
