The invention relates to a laser-electric arc composite heat source high-speed welding method of ultrahigh strength steel, belonging to the technical field of high-strength steel welding. The traditional laser-electric arc composite heat source high-speed welding method of the high-strength or ultrahigh strength steel has overhigh welding linear energy due to low welding speed and large energy input so as to cause the deformation of a welding workpiece; in addition, chevilled silk spacing is overlarge, and stabilization action realized by a laser is reduced because the laser is adopted firstly and the electric arc is adopted subsequently so that a welding process is unstable and easy to generate splashing. The invention adopts laser-electric arc composite heat source welding; the welding workpiece is the high-strength steel or the ultrahigh strength steel; an electric arc welding gun is used for welding firstly and a laser nozzle is used for welding subsequently during welding; the current of electric arc welding is 140-180A, and the voltage of the electric arc welding is 23-25V; an included angle theta between the electric arc welding gun and the surface of the workpiece is 60-65 degrees; the laser power is 3-5kW; the welding speed v is 1-3m/minute; and the chevilled silk spacing h between a laser beam and a welding stick is determined within a range of 1-3mm. The invention realizes the welding of the ultrahigh strength steel without preheating, cold cracks or deformation.

An internal bladder agitator member(s), which are free to travel in the retained fluid when the bladders are in the filled state.

Cellulosic biomass is reduced to a micropowder with particles having average diameters below 5-10 micrometers with a significant fraction of the particles have diameters below 1 micrometer. Biomass (e.g., wood, agricultural waste or other plant materials) is first processed into pieces having a maximum diameter of about 10 mm. This is then dried to reduce its water content to no more than about 15% by weight and introduced into a disruptor which reduces the particle size to about 1 mm. Next the biomass is processed with a disc mill where edges of rotating discs travel along a groove pressing and squeezing the biomass, thereby breaking the biomass pieces into smaller and smaller particles. The resulting micropowder is extremely susceptible to enzymatic or chemical hydrolysis into constituent sugars. In addition, the micropowder can be suspended in an air stream and burned directly to provide heat to boilers and similar devices.
